Lazare Kaplane Sues Photoscribe over Inscription Patents

International heavy hitter Diamond manufacturer Lazare Kaplan International (LKI) has sued Photoscribe Technologies alleging that Photoscribes's laser inscription of diamonds infringes on LKI's patent rights.


LKI alleges that two of their patents; Laser Marking System issued on 11/5/2002 and the Microinscribed Gemstone patent issued on 3/14/2006 have been infringed.


Photoscribe contends that it introduced it's laser inscription technology in 1999 after extensive due diligence including full disclosure to LKI in 2000 and that LKI lawyers at that time did not express any reservations or threathen litigation.


With growing consumer demand for laser inscription of their diamonds and gemstones as a valid form of identification, the timing of the LKI lawsuit at this juncture is curious.

Thanks for all the information. On a facet notice, how do you cope with all of the spam you get in your weblog? My new weblog is getting destroyed by random spammers and I have been spending a variety of time and power deleting feedback its simply not funny. . I get so drained fighting spam that I feed I should stop running a blog entirely.
