专利局无效程序

About

在激烈的市场竞争中,创新型企业往往要捍卫其专利的有效性或挑战竞争对手的专利有效性。审查专利局授权专利的程序非常复杂,往往涉及平行诉讼,这就要求律师深入了解诉讼程序之间的相互作用以及如何优化整体策略来确保各项诉讼的成功。无论是通过美国专利商标局(USPTO)专利审判和上诉委员会(PTAB)的授权后复审、德国专利商标局(DPMA)专利部或欧洲专利局(EPO)的异议,还是德国联邦专利法院的无效诉讼,飞翰都是代表客户处理这些程序最有经验的律所之一。我们已为200多个涵盖各个行业的企业客户代理专利无效程序、制定不同战略目标,积累了相当数量和类型的丰富经验。

我们代理请求人和专利权人案件业务均衡,并获得了各大奖项和排名、以及专注从业人员观察和评论的新闻媒体的持续认可。我们的成功在于深入了解相关法庭、规则、趋势和程序。我们每个月都会在PTAB博客发布我们跟踪的各类PTAB数据。此外,我们也会发布累积的PTAB数据。

Carrum Technologies, LLC v. BMW of North America, LLC, et al.

Obtained complete victory against Carrum on appeal of the District of Delaware’s claim construction to the Federal Circuit following Carrum’s stipulation of non-infringement under the claim construction, thereby exonerating BMW’s ACC system, first sold in 2000, against Carrum’s 2004 patents. Invalidated several asserted claims through post-grant efforts before the U.S. Patent Office, including IPRs and EPRs, and pursued claims through proceedings before the Eastern District of Virginia to vindicate BMW’s patent challenges.

Eye Therapies, LLC v. Slayback Pharma, LLC

Finnegan represented Bausch & Lomb’s licensee Eye Therapies, LLC in an appeal at the U.S. Court of Appeals for the Federal Circuit from a Patent Trial and Appeal Board (PTAB) decision finding Eye Therapies’ patent directed to a low-dose brimonidine treatment for eye redness (Lumify®) to be unpatentable. In a precedential decision, the Federal Circuit agreed with Finnegan’s arguments and found that the Board had wrongly invalidated the patent based on an incorrect claim construction, vacating and remanding the case back to the PTAB. The proceeding settled shortly thereafter
