Guardian Industries Corp & Honeywell International Inc., have filed suits in a US District Court against dozens of electronics companies worldwide for allegedly infringing their intellectual property relating to LCD technology. Flat glass maker Guardian & Honeywell (weapons systems mfr) are attempting to recoup royalties on their patents. Neither firm is in LCD production. Taiwan & S Korea are the two main centres of LCD production. The lawsuits target the LCD industry directly, but also assert claims against companies that incorporate LCDs into final electronic products. Privately held Guardian, asserts rights on four patents related to the design & manufacturing of LCD displays. The patents cover technologies that affect the viewing zone and high-contrast features of LCD displays, according to court papers.
