More activity in lithium battery litigations

An IPBiz reader noted that a re-examination certificate was issued on 22 April 09 on Armand's patent titled CATHODE MATERIALS FOR SECONDARY (RECHARGEABLE) LITHIUM BATTERIES [6,514,640]. See 90/008,205.

According to a document filed 22 Dec 2008, claims were amended.

As a footnote, LBE "replaced" Michel Armand in the Stanford lab of Robert A. Huggins when
Armand left for France. Initial work was on Croft's graphite/CrO3 "intercalation" compound, which was
determined to be a physical mixture of graphite and Cr308. Armand had reacted this material
with n-butyl lithium.
