Narrative Opinion Summary
In a patent infringement case, Tidel Engineering, L.P. accuses Fire King International, Inc. of infringing on two patents related to cash deposit and electronic lock systems, while Fire King counterclaims infringement of its patent by Tidel. The case primarily revolves around the interpretation of patent claims, with the court emphasizing the specification's role in guiding claim construction, as dictated by the Federal Circuit's decision in Phillips v. AWH Corporation. The court delineates the scope of terms like 'economy safe' and 'intelligent safe,' ruling that 'economy safe' excludes a PC board and printer, and 'intelligent safe' is not restricted to safes with a PC board. Additionally, the court addresses the applicability of 35 U.S.C. § 112(6) to terms such as 'data input means' and 'money dispensing mechanism,' clarifying their corresponding structures. The decision adopts agreed definitions for several claim terms while rejecting others that lack support from the specification. The court concludes by instructing both parties to adhere to the adopted definitions in future proceedings, ensuring clarity and precision in patent claim interpretation.
