  • "Intellectual Property on the Internet" - the book by Mr.Atanas Kostov


    Mr.Atanas Kostov - copyright attorney in Bulgaria. The book "Intellectual Property on the Internet".


    The reason to write the book "Intellectual Property on the Internet" is the fact that intellectual property is the most powerful regulator, and a protective mechanism against the processes that are currently happening on the Internet. You will ask why this is so important? Due to the fact that the full potential of the creative industries is already online and the same goes for the business, which means that in the near future any social, commercial, scientific, artistic or social activity will be mediated by the Internet. Even now, there is no good or service that is not available online, and this business model has been adopted by the electronic media and the show business. 

    All this leads to a justified interest of the users in this electronic phenomenon, which is related to the easy commodity turnover, quick access to specific works, goods or services, but also to the presumed will to "jump over the legal barriers" due to different motives. In addition to the old theme of internet piracy (which also has new dimensions in the development of legislation), there are already new unscrupulous practices aimed at "abducting" domains or registering such names under other company names or trademarks for resale or another type of commercial effect to the registrant, such as unfair competition and / or attracting additional user traffic. On the other hand, copyright and related licensing agreements have become as "electronic" as it calls for the need for new, credible and adequate legislative solutions to deter unscrupulous practices on the Internet. The strange thing is that the Bulgarian Law on Copyright and Related Rights as well as the Law on Marks and Geographical Indications "delay" to legally regulate the processes that concern intellectual property rights online, neither of which even mentions the word " Internet ", despite the increasingly dynamic e-business in Bulgaria. At the same time, special laws (which are not part of a copyright law or trademark law) specifically regulating legal relationships and infringements of intellectual property rights on the Internet have emerged in many foreign legislation. 

    This book gives a vision of some of the major topics and issues in the described context by trying to comment and at the same time propose solutions to address the issues of copyright, trademarks, domains and other business identifiers that are used in network. I hope this statement assures the reader how important it is in today's time to know the intellectual property legal tools that serve to prevent online business models as well as those relating to copyrights based on the Internet. The relevance of the subject is related to purely pragmatic and commercial motives regarding the proper structuring and protection of online entrepreneurship. The book gives many examples of national and international case law on case studies that deal with the exact subject of intellectual property rights in the web, in order to make these legal processes more accessible. My aim in the commented topic is to make it as accessible as possible not only to lawyers, but to the business community as well as to the representatives of the creative industries, without having to propose ready solutions, but with the option of giving a reflection on how to deal with analogous case studies.

  • "Internet Intellectual Property Law" in Bulgaria?


    "Internet Intellectual Property Law" in Bulgaria? Internet law. Internet attorney in Bulgaria.


    In the 21st century, literally every social, business, political, and cultural aspect of life is mediated by online space. This means that behind every everyday activity stands an online platform - a website, a blog, an Internet mobile application, and so on. The Bulgarian social reality shows that offenses / crimes aimed at copying, using, reproducing, distributing, hacking, breaking the integrity and functioning of online works are a practice that is completely neglected, legally unsettled, and therefore devoid of any clearly structured legislative sanction, therefore prevention. It is correct to note that there are some legal norms in the Bulgarian legislation which concern the commented subject, but they are in different material laws and provide for separate abstract hypotheses that do not communicate with each other and thus remain some "mutilated" legal constructions without real practical significance.

    All of this naturally leads to the total unproductiveness and almost zero efficiency in the work of specialized prevention bodies in the face of, for example, in the computer crime sector of so called “GDBOP”, due in particular to the lack of an adequate legal framework from a substantive point of view and respectively the lack of powers from a procedural point of view. This article aims to precisely identify these problems and to define what has been achieved so far internationally to justify the real need for such a legislative initiative in Bulgaria, which is justified not only in the present but also especially in the future, given the obvious all-round digitization of public life. Here I would like to point out the fact that the legal focus on online space and its problems has been placed in Western Europe and the US in the mid-1990s, i.e. the Bulgarian legislation is late for nearly 20 years to place emphasis on lawmaking in this sphere. I would like to mention that when in 2009 at a intellectual property conference, I started to speak on the subject of this article, I was greeted with silence and misunderstanding by a strictly professional audience that made me feel like a "stranger in my own." Unfortunately, there is no feedback between the online industry and lawyers, intellectual property specialists, which leads to a lack of communication and an option for a meeting of opinions, concepts and views to identify the specific problems to be solved. That is why, up to this day, I continue to insist that an "Intellectual Property Law on the Internet" must exist in the Bulgarian legislation, taking into account the balanced interests of users and rights holders, and in this context, the different options to the positive legal behavior of the different legal entities and a corresponding sanction in respect of offenses and crimes directed against copyright works and various technical and software platforms, object of intellectual property based on the Internet.

  • “Copyright Hypothesis" - book by Mr.Atanas Kostov



    Mr.Atanas Kostov - copyright attorney in Bulgaria. The book “Copyright Hypothesis".


    The book “Copyright Hypothesis" is the fruit of my synthesized ten-year experience as an intellectual property lawyer. The writing of every material in it is inspired by my work on a specific case, commenting on the legal basis and relevant case law. It is important to note that the purpose of writing the book is to be practical rather than to claim theoretical exhaustiveness. So I have selected and focused on this part of the texts of the Copyright and Related Rights Act, which are robbing, interesting and directly affecting the creative industries in Bulgaria. The bulk of the material in the book is a synthesis of theory and practice in the form of court decisions, which is systematically located for convenience at the end of each exhibition. How much current case law is adequate, internally uncontroversial and compliant with the legal framework, I have left to judge the reader myself, as the conclusions are obvious.

     I think that for this reason, the writing here will be useful not only for legal practitioners, but especially for the authors themselves - artists in the broad sense of the word, as well as architects, photographers, artists, designers, computer specialists and other professions, related to culture and science. Long contact with copyright issues of creative people has made me realize that they still do not have the courage, determination and legal culture to assert their rights to creators adequately. The reasons for this are of a different nature. Firstly, perhaps Bulgarian education does not offer these specialists the necessary knowledge and useful experience in the field of copyright and artistic management, which is particularly important in the context of a market society. Hence the lack of knowledge of the authors about the ways to protect their intellectual work, as well as the motivation to consult and seek specialized legal assistance in this field. Naturally, the well-developed jurisprudence of the courts and the prosecutor's office and, in my opinion, the little fuzzy criterion on the procedure and practical means of engaging and activating the administrative responsibility for copyright violations, a priority of the Ministry of culture. All this leads to a lack of trust in our society as to whether the protection of copyright in Bulgaria is real and working. Increasingly, in the public domain, there are data about successful measures in the field of copyright, but they concern mainly copyright and related rights of foreign authors and companies. The big question is is there a real protection for the rights of Bulgarian authors and what part of the case law shows a positive trend in this direction? 

  • Blockchain software patents. A new look at the future of the financial and public sectors.

     Blockchain software patents. Blockchain attorney in Bulgaria.


    Introduction. The liberalisation of the banking sector to crypto currencies and, above all, the blockchain technology behind them, shows that the financial market slowly breaks the shell of misunderstanding into the new online legal mechanisms that lead to software verifying each link in a legal deal. In my opinion, the crypto currencies themselves (as a speculative tool) in the near future are doomed to a total collapse of a single dollar denomination for a specific crypto (for example, "bitcoin"), but blockchain technology as an innovative business model and legal tool for doing business online, will soon develop technologically and enter various spheres of public life - finance, law, health, education, creative industries, public sector. A proof of this statement is that at present, perhaps the largest bank in the world - the US Bank of America - has a total of 50 patents in the field of blockchain technology serving the banking and financial sector. Оn the second position by applications for this kind of patents in US it is the giant in the computer industry IBM, which logically declare interest in this industry, as it has been for years the main hardware supplier (of various types of computer equipment) for thousands of banks around the world. 

  • Community trademark opposition common rules.


    Trademark opposition. Trademark attorney in EUIPO.


    Notice of opposition may be filed within a period of three months following the publication of the Community trade mark application. The official publication date is that which appears on the front cover of the Community Trade Marks Bulletin. The notice of opposition and payment of the opposition fee EUR 350 must be received by the EUIPO within this time limit. 

    EUIPO accepts a notice of opposition against a CTMA that is received by fax and/or post before the CTMA has been published; thus before the commencement of the opposition period. The opposition will be kept on hold and be deemed to have been filed on the first day of the opposition period, namely the first day after the publication of the CTMA in part A1 of the CTM Bulletin. 

    Payments must reach the EUIPO within the time limit specified for filing opposition, which is three months. However, provided that all the steps necessary for effecting payment are taken within this time limit, the Fees Regulation allows for payment to be considered as made on the condition that the following requirements are met: where payment is made by bank transfer, the payment order must have been given within the aforementioned time limit. However, if the payment order has not been made within the last ten days of the time limit specified, a surcharge of 10% will be payable. 

    The EUIPO has published Guidelines concerning the opposition proceedings which attempts to explain in detail the practical application of the provisions of the CTMR and the Implementing Regulation governing opposition proceedings. In addition, a form for filing notice of opposition is available from the Office, containing relevant explanatory annotations.

    In 2021, IUSATHOR was selected as the law firm of the year in Bulgaria. 

    The managing partner of IUSAUTHOR Law Firm is Atanas Kostov, a lawyer who is one of the top specialists in Bulgaria in the field of intellectual property, and he has focused his legal efforts in this area for 20 years. Atanas Kostov knows in detail the available international and national case law in copyright cases, and based on his experience and authority as a copyright specialist, he has been invited to participate in the Advisory Council on Intellectual Property at the Ministry of Culture, as well as a consultant in a working group of the legislative committee on some of the recent amendments to the Copyright and Related Rights Act. In his career, Atanas Kostov has written five books commenting in detail on copyright law and over 50 scientific articles in the same field, has participated in numerous seminars on copyright law as a lecturer, is one of the permanent authors of the prestigious legal publication "Labor and Law", has consulted numerous corporate clients and individual authors on copyright issues.

Intellectual property on the Internet is a key business aspect in the 21st century and Atanas Kostov is one of the few specialists in Bulgaria who are familiar in detail with the specific aspects based on the so-called "Internet law" in the online environment, both in national and international aspects.

    Concept of copyright. According to Article 3, paragraph 1 of the Copyright and Related Rights Act, the subject of copyright is any work of literature, art and science which is the result of creative activity and is expressed in any way and in any objective form, such as:

    - literary works, including works of scientific and technical literature, works of journalism and computer programs;

    - musical works;

    - works for the stage - dramatic, musical-dramatic, pantomime, choreographic, etc;

    - films and other audiovisual works;

    - works of fine art, including works of applied art, design and folk arts and crafts;

    - realised works of architecture and applied development plans;

    - photographic works and works created in a manner analogous to photography;

    - approved architectural projects, approved spatial planning projects, maps, schemes, plans, etc., relating to architecture, spatial planning, geography, topography, museums and any field of science and technology;

    - graphic design of a printed publication;

    - cadastral maps and state topographical maps.

    (2) Copyright objects shall also include:

    - translations and adaptations of existing works and folklore works;

    - arrangements of musical and folklore works;

    - periodicals, encyclopaedias, collections, anthologies, bibliographies, databases and the like, which include two or more works or materials.

    (3) A part of a work referred to in par. 1 and 2, as well as preparatory sketches, plans and the like.

    Over the past several years, IUSAUTHOR has worked closely with the U.S. Copyright Office on the registration of copyright works in the United States. This copyright registration regime covers all 165 member countries of the Berne Convention, including Bulgaria and most of the EU member states, and the registered copyright work is also listed in the US Library of Congress. In contrast to the European copyright system, where copyright in a work arises from the moment of its creation and publication in the public domain, and where there is no registration of copyright, in the Anglo-Saxon system, and in this case in the United States, there is a registration regime with respect to a specific copyright. Registration is done at the U.S. Copyright Office by carrying out a specific administrative procedure for registering the copyright work. IUSAUTHOR offers its clients this specific way of documentary protection of their copyright, which is an exception to the general European principle. Our clients are thus able to register their copyright internationally, with protection extending to virtually all developed industrial countries that are signatories to the Berne Convention. At this stage, most Bulgarian legal entities that decide to preserve their intellectual property in this way are authors of software, literary works, works of visual art (design) and architecture. 

    Copyright protection in the court. 

    Law Firm IUSAUTHOR offers you legal defense in administrative and criminal proceedings concerning copyright infringement, copyright tort claims under Article 95 et seq. of the Copyright Law, as well as in connection with criminal proceedings under Article 172a of the Criminal Code.

  • Copyrights on Facebook - theoretical and practical problems and solutions.

    Copyrights on Facebook. Copyright attorney in Bulgaria.


    The social network Facebook became a social phenomenon that accumulates much of the contemporary social, business, and cultural life of the world. Background information indicates that the site was created by Mark Elliot Zuckerberg, described as a genius programmer while still a teenager, and creator of projects like "Zucknet" (a primitive version of AOL instant messenger), a media player, called "Synapse Media player" (in which Microsoft showed interest), the program "Course Match", which helps students to choose courses, and the so-called "first Facebook"- the site Facemash. This internet site allowed users to compare pictures of classmates and select the one that is "coolest.” Facemash worked just one weekend because of huge site traffic overloads caused an interruption of internet service at Harvard (where Zuckerberg was a student at the time). Post factum Zuckerberg was criticized for this by the student newspaper, as well as classmates, because he used their photos without proper authorization. Given these negatives, Mark Zuckerberg started programming Facebook which was launched on the Internet from his room at Harvard on Feb. 4, 2004. At present, this internet site is owned by Facebook Inc., based in Silicon Valley, California, USA. On 21 July 2010, the youngest billionaire in the USA - Mark Zuckerberg (6.9 billion dollars personal assets) officially reported that the site has reached 500 million users worldwide. An interesting fact is that in 2010, Steven Levy - author of the book "Hackers: Heroes of the Computer Revolution", said that Zuckerberg described himself as a "hacker.” Therefore, at present, Facebook Inc., holds contests called "hackathons" every two months. The goal is for participants to program, present, and complete a software project in a single night. Facebook provides music, food, and beer, and the event is usually attended by participants of the Facebook site, including Zuckerberg. Some people say that Zuckerberg used these hackatons to recruit employees for his company in the beginning, and even today.

    1. Patent registration in Bulgaria. Procedure.

    The right to apply for a patent belongs to the inventor or his successor in title. An inventor who is a resident or has a registered office in the Republic of Bulgaria may file a patent application with the Patent Office either in person or through a Bulgarian industrial property agent. An applicant who does not have a domicile or registered office in the Republic of Bulgaria must file his invention application with the Patent Office through a local industrial property representative.

    The filing date of the patent application shall be the date of receipt at the Patent Office of the patent application containing the name of the invention, the name and address of the applicant, the name and address of the inventor and a description of the invention disclosing its nature, claims, drawings (if necessary for clarification), and an abstract. A declaration of the actual inventors should also be submitted with the application in cases where the applicant is different from the actual inventor. If the patent application is filed through an industrial property representative, the name, address, contact telephone number and email of the representative shall be indicated in the application, and the representative's power of attorney shall be attached to the application. Where priority is claimed, the application shall indicate the number, date and country of the priority document. In such cases, a priority certificate shall be submitted with the application.

    If the applicant for a patent is willing to grant a licence to it, a declaration of willingness to license shall also be attached.

    The application must be accompanied by proof of payment of the application, formal examination, preliminary examination and eligibility, claim and priority fees, if any. The patent application documents shall be submitted in Bulgarian. Where the description, claims, drawings and abstract are submitted in another language, they shall be submitted in Bulgarian within three months in order to preserve the filing date. Any application for which the applicant is a Bulgarian citizen with a permanent address in the Republic of Bulgaria or a legal entity with its registered office in the Republic of Bulgaria shall be subject, within one month from the date of filing, to a security check for classified information.

    Within 13 months from the date of filing of the patent application, or the priority date, the applicant may file a request for examination and examination. By filing the request, the applicant must pay a fee for examination and examination of the patent as well as a fee for publication of the application. Upon filing the application and paying the examination and examination fees, the application is published on the 18th month and subsequently examined and examined for novelty, inventive step and industrial applicability.

    If the applicant fails to file a request for examination and examination of the patent or fails to pay the fees, he may file an application for transformation of the patent application into an application for registration of a utility model. This application must be filed no later than 15 months from the filing date of the application, or its priority date. If no such request is filed, the application shall be deemed to have been withdrawn. In practice, the registration of a patent can be completed in about 19 months if you work with a professional and he/she tries to strictly comply with all the deadlines specified by the Patent Office.

  • Registration of Community trademark(EUTМ).

    Trademark registration in European Union. Trademark attorney in EUIPO.


    A European Union Trade Mark (EUTM) is any trademark which is pending registration or has been registered in the European Union as a whole (rather than on a national level within the EU).

    The EUTM system creates a unified trademark registration system in Europe, whereby one registration provides protection in all 28 member states of the EU. The EUTM system is unitary in character. Thus, an objection against an EUTM application in any member state can defeat the entire application, an EUTM registration is enforceable in all member states.

    The EUTM system is administered by the European Union Intellectual Property Office (EUIPO), which is located in Alicante, Spain (see also trade mark law of the European Union).

    The Community trademark gives its proprietor a uniform right applicable in all 28 Member States of the European Union on the strength of a single procedure which simplifies trademark policies at European level. It fulfils the three essential functions of a trademark at European level: it identifies the origin of goods and services, guarantees consistent quality through evidence of the company's commitment to the consumer, and is a form of communication, a basis for publicity and advertising.

  • Software patents. International and national regulations.


    Software patents. International regulations. Software attorney in Bulgaria.


    The topic of software patents proved controversial and very interesting in modern times due to the intermingling of serious business interests with consumer rights and the authors of the software works that need protection . On the other hand the existing problems relates purely legal collisions occurring in existing contradiction between the doctrine and the overlap in that rule concerning the copyright regulations of the software as a literary work (according to Article 10 of the Berne Convention - see . Editing from 1971 . ) As opposed to Anglo-Saxon principle view that software can be fit proprietary , ie patentable . The text of Article 10 of the " Berne Convention for the Protection of Literary and Artistic Works " is explicitly enshrined rule that " computer programs , whether in source or object be protected as literary works under the Convention ." Several years later, in standard conditions, the World Intellectual Property Organization , published in 1978, reflected the definition of the term " computer program " as " a series of instructions that are embodied in a machine readable medium , so as to make the machine that has the ability to process information , to indicate execute and achieve a particular function , task or result." It can be considered that this is the definition and the notion of "software." This conclusion was reached because of the fact that the title of "generic terms of "World Intellectual Property Organization is the " protection of computer software." Background This leads me to the view that the international system of software patents has developed in different countries of the world with different dynamics , the concept of their legislative framework is in change . They range from the initial installation of the software as being fit first object of copyright and then patent law , to modern - think highly exaggerated argument that software as a success of the creative industries and science should not be " monopolized " by patents business and has become one of the free and free achievements of society.

    1.Software patents in the Anglo -Saxon patent system. Patent law of the United Kingdom at present is entirely consistent with the meaning of " European Patent Convention" , in this sense, computer programs are beyond the scope of patentability requirements . Case law of England , however, argues that the alleged invention can be viewed as a patent only if it provides a real contribution , which is of a technical nature . Therefore, a computer program concerning concepts for business process can not be registered as an invention , but a computer program to implement the industrial process may be suitable object of patent law.

  • The book "Copyright in Architecture".


    The book "Copyright in Architecture" - authors Mr.Atanas Kostov  - copyright attorney and Mr.Jordan Pangev - attorney at law.


    The Copyright and Related Rights Act addresses the most important issues concerning the rights of design architects. The enforcement of these legal norms has accumulated many inconsistencies and disputes that cause problems in the actual protection of copyright holders of architectural projects and works of architecture, and create ambiguities in the relationship between investors and authors - architects and civil engineers. And this circumstance does not correspond to the prevailing logic in Bulgarian copyright law.

    The book offers an in-depth comparative legal analysis between Bulgarian law, the European and Anglo-Saxon legal systems. On this basis, the problems are defined and solutions are formulated both for action under the existing legal framework and for its correction. Model contracts have been developed that reflect models for resolving contractual relationships between authors of architectural works and their users. Thus, the publication will help to unify the practice and take appropriate legal action on the settlement of architectural rights - adequate to the current legal framework in Bulgaria.

  • The hottest blockchain startups in Bulgaria.

    The hottest blockchain startups in Bulgaria.


    Bulgaria and local dev community haven’t been too vocal about this, but it seems that the country has an important stake in the global blockchain ecosystem. With a growing community around the technology (not the fading crypto enthusiasm), the global acceleration program of platform Aeternity for blockchain startups and the investment company Belayer based in Sofia, a Balkan Blockchain Association seem to be well positioned on the map.

    Currently, there are around 30 companies in Bulgaria, both service and product-oriented ones, which leverage blockchain technology in an attempt to develop viable products that serve real business needs. “The majority of blockchain companies right now are part of the transition from a centralized to a decentralized economy. A lot of them are still using decentralized components to solve problems but still have a centralized point of strategic decision-making. The most interesting projects are the ones that change the whole paradigm and really manage to confirm the viability and sustainability of decentralized models of governance and operation. This will not happen overnight.”, Vladislav Dramaliev from aetertnity, told us.  Currently, there are around 30 companies in Bulgaria, both service and product, which leverage the blockchain tech in one way or another, in attempt to develop viable products that serve real business needs.

    Here’s the list of the scalable product projects that might have found a way to utilize the technology to solve problems, instead of finding the problem for the blockchain solution. We’ve mostly looked at products beyond the crypto bubble. You can find below what is each of them doing.

  • The patent attorney Mr.Atanas Kostov - Coronavirus vaccine is patented.

    The patent attorney Mr.Atanas Kostov - Coronavirus vaccine is patented.


    In an interview on bTV, Mr. Atanas Kostov as a patent attorney said that researches and patents on coronavirus date back to 2003. There are quite different types of coronaviruses and scientists around the world have been working on the subject for quite some time. "I began to investigate for personal interest whether there were patents in the field," said Mr.Kostov.

     "I came across one of the latest patents, which is from 2014. The research team working on it is English, and behind it is an English university". Mr.  Atanas Kostov explain on BTV this Sunday, that English scientists work on patent, who covers the coronavirus to protein 16. The modern coronavirus is a three-protein mutation on top, which is not what the patented vaccine was patented for" he said. 

    "The vaccine I'm talking about is a specific coronavirus that is related to the treatment of bronchitis. Currently, the complications affect the respiratory system and the deaths end with pneumonia. Perhaps that is where scientists' efforts should be directed " Mr.Atanas Kostov said. According to him, it is obvious that the British scientists are making progress on the subject and most likely there will be a positive result. 

    In some articles, British scientists pretending that they are on the verge of finding a treatment solution for the modern coronavirus and a vaccine for it.

  • The patents in the field of the Artificial intelligence.

    Artificial intelligence patents. Law practice. 


    The topic of artificial intelligence is still not present in Bulgarian law as something normative and practical, which is on the legislative agenda in the 21st century, not only for technological and legal reasons, which undoubtedly determines the future of the innovative sector and through it the public, business and personal life of every modern person. The latest research on the subject in many of the world's advanced technology countries has shown that it is not far off the time when besides the afternoon chess game with some electronic device, artificial intelligence will be issued with instant visas, will be approved faster and secure (personal data - finger, face recognition) bank credits, national and cross-border (eg European) elections will be held and health services will be provided. Other studies have shown that artificial intelligence will replace many professions - lawyers, notaries, bailiffs, judges, revolutionize medical precision and monitoring, robotize our industry, services and lifestyle, thus putting new intellectual, philosophical and psychological challenges to everyday life and perhaps to the relationships between us - human beings. Realizing the inevitability of all this, many companies operating in different spheres of social and business life began to develop dynamic and focused inventions based entirely on artificial intelligence. Taking this into account, I want to pay close attention to this statement of these patents, driven by my belief that today's inventions in the area of ​​Artificial Intelligence (AI) are the basis of our more interesting tomorrow.

    1.Historical development. Artificial Intelligence (AI) appeared in the 1950s, with the first mention of the term coming from a summer 1956 research project of Dartmouth College, New Hampshire, USA. A year earlier, in 1955, John McCarthy, a young assistant professor of mathematics at Dartmouth College, decided to organize a group for exploring and developing digital thinking machines. McCarthy selects the name "Artificial Intelligence" as a "new field" of scientific search. It presumes mostly neutral neutrality in order to avoid focusing on the narrow theory of automation and cybernetics, as already known achievements of analog technology. In early 1955, Mr. McCarthy turned to Robert Morrison, director of biological and medical research at the Rockefeller Foundation, to request funding for the Dartmouth summer seminar for about 10 mathematicians. On 2 September 1955, the project was officially presented to the board members under the notion of "artificial intellect".
