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.


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 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.

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? 



Mr.Atanas Kostov - trademark attorney in Bulgaria. The book "Opposition of the trademark"".


The book "Opposition of the trademark" reviews the new procedure for refusal of registration on relative grounds, which came into force with the latest amendments to the Law on Marks and Geographical Indications (LPMO) of 10.03.2011. Writing the book aims to make it useful to a wide range of lawyers, patent attorneys, industrial property representatives, commercial subjects, students, and citizens to give more clarity about the opportunities for opposition that the opposition offers. Most of the material in the book is a synthesis of theory and practice, primarily of OHIM and of the Court of Justice of the European Communities, mainly due to a lack of national practice for the time being, this approach being chosen to shed light on the specifics of the procedure not only on a national but also on a European scale. I believe that the judgments of the Court of Justice of the European Communities, as set out in detail, with clearly defined legal criteria relating to the opposition, would be directly applicable in practice and law enforcement in Bulgaria, not only because of their priority importance for Bulgarian legislation, but above all in relation to the competent legal opinions they actually offer.

For the reasons given, the introduction of the opposition procedure, in my opinion, is the result of a positive legislative initiative of the Bulgarian Patent Office. However, the opposition puts forward a number of theoretical and practical issues that will still be looking for its right solution. Dynamically evolving market realities and related legislative processes on a national and European scale have called for modern mechanisms to identify real-life traders in a particular business area, including intellectual property, in particular trademarks. I say this for several reasons. Firstly, because some of the registered trademarks in Bulgaria do not have any real commercial interests, they are registrated for themselves (in most cases for commercial purposes) and should be dropped as unusable for the reasons mentioned. Second, many unscrupulous practices are being monitored, which must be pirated at the trademark registration phase - a claim by the proprietor of the trademark owner, or a misappropriation of trade marks already entered but unregistered. Thirdly, competitive relations require continuous control efforts by applying appropriate legal measures to potential competitors - for example restricting the application of similar trademarks for identical or similar goods and services. Last but not least, the procedure in the Patent Office itself will be optimized by avoiding the subjective factor in the process of expertise, as until now the similarity as a relative ground for trademark denial was followed by a specific expert at the Patent Office, which was the case file of the respective trademark was distributed and this decision depended on his subjective opinion. Thus, marketers will be self-regulators of their own rights with respect to their registered and correspondingly trademarked trademarks, thus giving preference to a more practical and at the same time democratic approach to marketers. All this will, in my opinion, lead to a more efficient work of the Patent Office itself, which will significantly optimize its administrative potential.

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.
