Patent portfolios often span multiple related entities – a parent corporation and its subsidiaries, spinouts, or partners. When patent applications share overlapping subject matter, a US Patent Examiner may raise an obviousness type double patenting (ODP) rejection. The usual fix, a terminal disclaimer (TD) pursuant to common ownership, is not available when the patents are owned by different entities. This can have very real effects when a parent company assigns some patent applications in a portfolio, such as application-focused patents, to one wholly owned subsidiary while other foundational patents remain with another wholly owned subsidiary. IP attorneys Grant Ehrlich and Kim Vines take a look at double patenting and more in this Stites & Harbison Client Alert.

Recent changes at United States Patent and Trademark Office (USPTO) are reshaping the dynamics of patent prosecution, creating both opportunities and challenges for patent Applicants. The USPTO has recently implemented the Streamlined Claim Set Pilot Program and discontinued the Accelerated Examination program, leaving Track One and the Patent Prosecution Highway (PPH) as the remaining primary options in the US for expedited examination. The USPTO has also restructured examiners’ working conditions, revised or eliminated review procedures, revamped how backlog applications are handled, and introduced a second tier patent examiner position for AI development in an effort to reduce patent pendency.
