Case Brief Summary & Legal Analysis
tl;dr: A company that acquired a patent licensee through a statutory merger was sued for infringement. The court held that the non-transferable patent license did not automatically pass to the successor corporation, affirming that patent licenses are personal and non-assignable unless expressly permitted.
Legal Significance: This case establishes that under federal patent law, a non-transferable patent license does not transfer to a surviving corporation by operation of law in a statutory merger. It reinforces the default rule that patent licenses are personal and non-assignable absent express language to the contrary.

Case Facts & Court Holding
Key Facts & Case Background
PPG Industries, Inc. (PPG) and Permaglass, Inc. entered into a patent license agreement concerning ‘gas hearth technology.’ Under the 1964 agreement, PPG granted Permaglass a ‘non-exclusive, non-transferable, royalty-free’ license for two PPG patents. The agreement also granted PPG an exclusive license to nine Permaglass patents, subject to a reserved ‘non-exclusive, non-transferable’ license for Permaglass’s own use. The agreement explicitly stated that the license granted to Permaglass was ‘personal to PERMAGLASS and non-assignable’ without PPG’s written consent. A separate clause provided for immediate termination of the license to the two PPG patents if a majority of Permaglass’s stock became owned by a glass manufacturer. In 1969, Permaglass merged into Guardian Industries Corporation (Guardian), a glass manufacturer. Guardian, believing it had acquired Permaglass’s license rights through the merger, continued to use the patented technology. PPG filed suit against Guardian for patent infringement, arguing the licenses were personal to Permaglass and did not transfer to Guardian.
