Speculation about Halozyme's imminent lawsuit contributed to a sharp decline in Alteogen's stock price, resulting in a lost market capitalization of over 8 trillion won within just ten days. Meanwhile, MSD filed a request to the U.S. Patent and Trademark Office aiming to invalidate Halozyme's patent, indicating its proactive strategy in addressing potential liabilities associated with the patent dispute.

3. Overview of the Patent Dispute

  • 3-1. Background of the Patent Dispute

  • The patent dispute centers around the immuno-oncology drug Keytruda and involves Merck (MSD), Alteogen, and Halozyme. In 2020, MSD transferred Alteogen's SC formulation change technology called 'ALT-B4' for $3.865 billion (approximately 5.42 trillion won) and made an additional payment of $452 million in February to acquire rights to 'Keytruda SC Monopoly.' Subsequently, the clinical trial associated with this technology was successfully completed, with plans for a market release in the upcoming year. The conflict emerged as Halozyme sought to contest this technology, having initially overlooked the SC formulation technology market. As rumors of potential legal action by Halozyme spread, panic ensued in the market, leading to a significant drop in Alteogen's share price, with the company's market capitalization plummeting over 8 trillion won within ten days.

  • 3-2. Involvement of Halozyme in the Dispute

  • Halozyme's role in the patent dispute is pivotal, as it has expressed intentions to challenge Alteogen's technology. Vice President Jeon Tae-yeon of Alteogen publicly addressed market concerns, stating that 'ALT-B4 has no potential to infringe on competitors’ patents.' In a preemptive move, MSD filed a request to the US Patent and Trademark Office to invalidate Halozyme's patent to protect both itself and Alteogen from possible litigation. The disparity in patent scopes is crucial, with industry insiders suggesting that Alteogen’s technology, which applies hyaluronidase from various mammals, is superior to Halozyme's narrow patent, which is based primarily on human hyaluronidases.

  • 3-3. Market Reactions and Stock Price Fluctuations

  • The market reacted sharply to the unfolding patent dispute, particularly in response to rumors of impending legal action from Halozyme. Shares of Alteogen saw a significant decline, attributed to reports from investment entities like Goldman Sachs which speculated on potential patent litigation. This environment of uncertainty resulted in substantial financial losses for shareholders, characterized by the loss of over 8 trillion won in market capitalization in under two weeks. Analysts recognize that such fluctuations are typical in the pharmaceutical industry, especially when large corporations like MSD utilize patent invalidation strategies as a tactic against smaller biotech firms ahead of new drug launches.

4. Legal Proceedings and Patent Invalidation Requests

  • 4-1. MSD's Request for Patent Invalidation of Halozyme's Patent

  • Merck (MSD), a major global pharmaceutical company, has initiated a request for patent invalidation concerning Halozyme's patent with the U.S. Patent and Trademark Office (USPTO). This request is part of MSD's strategy to challenge the validity of Halozyme's intellectual property and was motivated by the desire to strengthen its own market position regarding Keytruda. Industry experts note that multinational pharmaceutical companies often engage in such legal maneuvers against smaller biotech firms ahead of launching new drugs. This can be seen as a common tactic aimed at reducing competition and securing commercial advantages.

  • 4-2. Alteogen's Response to Patent Infringement Claims

  • In response to MSD's patent infringement claims, Alteogen has firmly dismissed the possibility of infringing on Halozyme's patents. Vice President Jeon Tae-yeon, responsible for patents at Alteogen, stated in an interview that their platform technology (ALT-B4) has been thoroughly evaluated and confirmed to pose no risk of patent infringement. Alteogen conducted a comprehensive review of potential patent issues prior to entering technological agreements with MSD and Daiichi Sankyo.
