Sanders, Stannum settle suit over ‘Razor’ patent technique

NEW YORK — Lead recycler Sanders Lead Co. Inc. and Stannum Group LLC, Stannum International LLC, and S.P. Metals Inc. have reached a settlement over a lawsuit concerning the enforcement of a patent for a lead-refining technique.

Both Sanders and the defendants recently filed a joint stipulation of dismissal, as the parties "have settled Sanders’ claims for relief against defendants and defendants’ counterclaims for relief against Sanders asserted in this case," documents filed in U.S. District Court in Alabama show.

The case was subsequently dismissed "with prejudice, all attorneys’ fees, costs of court and expenses borne by the party incurring same" on Wednesday by Judge Mark Fuller.

"Sanders and Stannum have entered into a settlement agreement to terminate the dispute. A license agreement exists between Stannum and Sanders to use ‘the Razor process,’ " Stannum manager Jack Scott told AMM on Thursday.

"Sanders got what it needed," Joseph Bird, the attorney representing Sanders in the lawsuit, told AMM, noting that "we filed (the lawsuit) to invalidate some patents."

Troy, Ala.-based Sanders filed a lawsuit in April, alleging that the defendants had obtained a patent for a process to remove tin from lead called the Razor process, and wanted Sanders to pay royalties for using the process (, April 9).

Sanders claimed the process was developed in conjunction with its own employees in September 2005, thus invalidating the patent. The defendants filed a counterclaim in May.
