Narrative Opinion Summary
In this case, Cyrix Corporation filed a lawsuit against Intel Corporation, with SGS-Thomson intervening to assert rights as the assignee of the Intel-Mostek license. The primary legal issues revolved around whether SGS-Thomson was the rightful assignee of this license and if Intel was barred from contesting this assignment due to doctrines like waiver and equitable estoppel. Additionally, the applicability of the Patent Exhaustion Doctrine was examined in relation to Intel's infringement claims against Cyrix. The court found that the Mostek-Intel Licensing Agreement was validly assigned to SGS-Thomson, allowing them to manufacture and sell products under Intel's patents. Intel, through its conduct and prolonged acquiescence, was found to have ratified this assignment and was therefore precluded from disputing it based on equitable estoppel and laches. Furthermore, the Patent Exhaustion Doctrine was deemed to apply, as the transfer of FasMath coprocessors to Cyrix exhausted Intel's patent rights, preventing further claims of infringement. Thus, SGS-Thomson was upheld as a rightful licensee, and Intel's claims against Cyrix were dismissed, pending further trial on antitrust and unfair competition claims.
