Case Law Review: Volume 11, No. 4
Hauptman Ham’s April 2025 Case Law Review examines four important intellectual property decisions addressing patent claim drafting, patent term extension, Section 337 domestic-industry requirements, and trademark priority. This issue discusses written-description support for Jepson claim preambles, the proper start date for patent term extension of reissued patents, protection for patented products manufactured abroad, and limits on using the zone of natural expansion doctrine in trademark disputes.
