A summary of Southern California-related business litigation developments during the past week.

Lens Suit Settled for $5.3 Million: Optical Radiation Corp. has agreed to pay a Southern California ophthalmologist $5.3 million to settle a patent infringement suit stemming from the company’s manufacturing of multi-piece intraocular lenses, which are implanted in cataract patients. A federal judge had ruled earlier that the Azusa company had violated ophthalmologist Ronald P. Jensen’s patent on lens manufacturing. After the ruling, Optical Radiation altered its production of lenses so as not to infringe on Jensen’s patent. Of 1.3 million cataract operations in the United States annually, 97% include intraocular lens implants. (Case No. 86-4323. Settled Dec. 31, 1990).
