Honeywell files patent suit

Honeywell has filed a lawsuit against 34 electronics companies claiming infringement of a Honeywell patent for technology that improves the appearance of LCD displays.

Honeywell has filed a lawsuit against 34 electronics companies, including Apple Computer, claiming infringement of a Honeywell patent for technology that increases the brightness of images and that reduces the appearance of certain interference effects on a liquid crystal display (LCD).

According to a recent news article in Macworld, Honeywell alleges that Apple and the other defendants are violating US Patent 5,280,371. Filed in July of 1992 and granted in January, 1994, the patent describes a “directional diffuser for a liquid crystal display.”

Honeywell’s lawsuit claims the company’s patented technology is being used in a variety of consumer electronics products, including notebook computers, cell phones, personal digital assistants, portable DVD players, portable LCD TVs, video game systems, and digital still cameras.

Other companies named in the suit read like a who’s who in the computer and electronics business. Leading names include Sony, Toshiba, Nikon, Olympus and Eastman Kodak.

“Honeywell invests millions of dollars in research and development every year, and we aggressively defend our intellectual property to protect that substantial investment,” said John Donofrio, Vice President of Intellectual Property at Honeywell.

Honeywell’s lawsuit, filed in US District Court for the district of Delaware, asks for monetary damages and an injunction to prohibit selling products that infringe its patent.

“The two largest LCD manufacturers, LG.Philips LCD and Samsung Electronics, have previously taken licenses under this fundamental patent,” added Donofrio.
