Recently, the Supreme People’s Court upheld the patent validity for “a long-span highway anti-glare isolation net” (patent number: 201720386235.8) in the final instance of the second instance. The patent protection process was represented by our patent attorney.

案例背景

The patent application for “A long-span highway anti-glare isolation net” was submitted in 2017. In 2021, the patent owner discovered infringement in the market and immediately cooperated with our firm to launch a comprehensive rights protection campaign.

持续的维权努力

在过去的几年中，侵权人不断尝试挑战该专利的有效性，共提出了三次无效请求。然而，凭借我事务所专业团队的深厚技术背景和法律经验，每一次都成功地为专利权人提供了强有力的支持。经国家知识产权局审查后，均维持了该专利权的有效。

侵权人不服国家知识产权局的决定，两次提起了一审行政诉讼。我们事务所在两次一审中均协助客户取得了有利判决。

终审裁定的胜利

After that, the infringer appealed one of the invalidation decisions to the Supreme People’s Court. Recently, the Supreme People’s Court made a final judgment of the second instance, rejected all the plaintiff’s requests, and upheld the first instance judgment, that is, the decision made by the State Intellectual Property Office that all patent rights are valid. This judgment once again affirmed the professional level of our firm in the process of patent application writing and rights protection.

案件启示

1.专利申请文件撰写的重要性：最初的专利申请文件是后面十年、二十年专利维权的基础，这些白纸黑字在维权活动中发挥着极其重要的作用。全面布局的申请文件不仅有助于申请阶段审查通过，也在后续维权中发挥了关键作用。

2.全面的前期准备：专利保护始于充分的准备。初期的技术文档撰写、审查过程的细致应对，决定了专利在法律挑战面前的稳固性。对可能的无效理由提前做好应对策略，能显著提升维权的成功几率。

3.坚持不懈的维权态度：在面临侵权和无效挑战时，专利权人和代理机构的坚韧态度至关重要。持续提供法律支持和坚决的维权行动，能够有效抵御侵权方的各种挑战，最终维护专利权人的合法权益。

4.法律和技术的结合：有效的专利维权不仅依赖于法律知识的精通，更需要对技术细节的深刻理解。代理机构需在法律和技术两个方面同时具备专业知识，才能在复杂的专利无效挑战中游刃有余。

5. The importance of judicial procedures: By actively participating in administrative litigation and judicial procedures, the company achieved final victory in the Supreme People’s Court, demonstrating the key role of judicial procedures in patent rights protection. Firmly safeguard patent rights through legal means and ultimately obtain a favorable verdict.

6. Cooperation and trust: Close cooperation and high trust between the patentee and the agency are the foundation for successful rights protection. The agency’s deep understanding of and rapid response to the patentee’s needs ensures the efficient advancement of rights protection actions.
