Discussing patent strategies for innovation in the pharmaceutical and bio industry
Attorney Lee Il-hyung presents evergreen strategy and patent strategy plan
The Evergreening Patent Strategy Seminar, hosted by National Assemblyman Choi Bo-yoon's office (People Power Party, affiliated with the National Assembly Health and Welfare Committee) and hosted by Daeryun Law Firm's Medical Pharmaceutical Group, was successfully concluded on January 24 in the conference room of Daeryun Law Firm's headquarters in Yeouido, Seoul.
At the event, National Assembly member Choi Bo-yoon (People Power Party), Kim Kuk-il, CEO of Daeryun Law Firm (Limited), Lee Il-hyung, attorney at Daeryun Law Firm (Limited), and other pharmaceutical and bio industry workers attended the event to share issues related to Evergreening's patent strategy and plan a future direction. This seminar was also attended online through a live broadcast and webinar through the official YouTube channel of Daeryun Law Firm (Limited).
Attorney Lee Il-hyung, a former in-house lawyer at Celltrion, who was the presenter, introduced major precedents related to pharmaceutical patents and shared various patent strategies currently being applied by pharmaceutical and bio companies and points to keep in mind when applying for patents.
Evergreening is a method for companies to continue to maintain profits through follow-up patents even after the expiration of existing material patents. Even if a pharmaceutical company succeeds in developing a new drug with great difficulty, the price of the drug plummets after the patent expires, and the need to establish such a strategy to maintain the patent for a longer period of time arises.
Attorney Lee emphasized that this strategy can be a powerful weapon for original pharmaceutical companies and that endless opportunities are created for pharmaceutical companies that understand and respond well to patent strategies.
He then presented patent strategy plans such as formulation patents, composition patents, salt change patent applications, isomer patent applications, hydrate/crystal form inventions, and dosage/administration method improvement patent applications. In addition, specific actual cases were analyzed and related legal services such as prior art search, patent avoidance strategy design, patent application, and patent infringement litigation were introduced.
People Power Party National Assembly member Choi Bo-yoon, who hosted the seminar that day, said, “As interest in specific cases and designs of evergreening specialized strategies in the pharmaceutical industry has grown, I hope that today’s seminar will serve as an opportunity to learn more closely and prepare countermeasures. As a member of the National Assembly’s Health and Welfare Department, I will also do my best for the pharmaceutical bio industry.”
