Trimble Navigation, Ltd. v. RHS, Inc. (PDF)
Decided Sept. 17, 2007
Judge Hamilton

Judge Hamilton construes one disputed claim term in this clarifying claim construction order. The patent at issue relates to a

GPS-based guidance system[s] for agricultural farming capable of recognizing operator-induced deviations made by the operator of a vehicle while driving a spraying device … down a field.

Trimble interpreted the courts construction of the term “form line” in the original claim construction order broadly – a premise from which it’s entire infringement analysis stemmed from. The court supplemented its original construction to further define the meaning of the term, narrowing the scope of the claim’s construction from that furthered by Trimble.
