The Doctrine of Claim Differentiation: Who Got It Right in Retractable Technologies?

Whether the term “body” encompassed “multi-piece” structures became the crux of the claim construction issues in Retractable Technologies. The District Court for Eastern Texas, apparently applying the doctrine of claim differentiation, construed independent Claims 1 and 43 to cover a “body” which might be a “multi-piece” structure. Accordingly, the District Court denied post-trial motions by the alleged infringer (Becton Dickinson or “BD”) to overturn the jury verdict that BD infringed these Claims of the ‘224 patent. Judge Lourie (writing for the panel majority) reversed the District Court, ruling that the term “body” was limited to a “one-piece” structure in light of the ‘224 patent specification.
