CRU Faster Than Before AIA, Provides Options for Patent Owners
Patent reexamination filings have fallen 86% since 2012. With the elimination of the popular inter partes patent reexamination option in 2012, an overall decrease was certainly expected. However, ex parte reexamination filings continue to drop every year. Only 191 ex parte reexamination requests were filed in 2017. This was the lowest number of ex parte reexamination filings since the mid-1990s. While an ex parte patent challenge is far less appealing to a patent challenger than a contested proceeding (AIA trial proceeding), and this factor has undoubtedly contributed to the decreasing numbers, patent reexamination and other post-grant proceedings of the Central Reexamination Unit (CRU) still provide unique rehabilitation opportunities for patent owners.
