1. Restrict the development and innovation of medical technology: The purpose of medical patents is to encourage innovation and research and development of new drugs and treatments. However, excessive protection of medical patents may restrict other researchers and companies from further research and innovation with existing knowledge, thus hindering the development of medical technology.
2. Obstructing the popularization and accessibility of drugs: Patent protection gives pharmaceutical companies the power to monopolize the market, making it impossible for other companies to produce the same drugs and compete with them during the patent period, which may lead to high prices of innovative drugs and bring economic burdens and obstacles to many patients.
3. Abuse of patent rights to extend the patent term: Some pharmaceutical companies may abuse patent rights and extend the patent term by strategically maintaining invalid patents, further delaying the time for other companies to produce similar drugs. This kind of abuse does not conform to the original intention of the patent system and should be restricted and cracked down.
