Uship Intellectual Properties, LLC v. United States
102 Fed. Cl. 326
Fed. Cl.2011Background
- This court previously construed the preambles of the '220 and '014 patents as limiting to a method using an automated shipping machine for at least some steps.
- The court also construed the term “validation” as performing two functions: validating receipt and validating that the item is the one for which a label was printed.
- USHIP filed a Motion for Reconsideration on May 27, 2011 challenging the construction of “validation.”
- The Government and IBM submitted responses opposing USHIP’s interpretation; USHIP replied in July 2011.
- The court granted-in-part and denied-in-part USHIP’s reconsideration, reaffirming that the validation function is performed by an automated shipping machine, though acknowledging nuances in the prosecution history and embodiments.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether prosecution history disclaimer applies to restriction-response statements | USHIP argues no disclaimer applies to restriction responses | Government contends prosecution history supports machine-only validation | Discretionary—court sides with nuanced consideration, not a flat disclaimer |
| Whether the fourth embodiment’s attendant validation undermines machine-only validation | Attendant validation is functionally equivalent to machine validation | Fourth embodiment does not require attendant for validation | Court rejects attendant-only reading; machine validation remains essential for claim 1 |
| Whether prosecution history supports the court’s original construction | Statements were not unambiguous disavowals | Prosecution history shows machine-performed scope | Prosecution history supports machine-performed validation as the proper construction |
| Whether the patent specification permits attendant-performed validation in any form | Specification shows a permissible attendant role in validation | Specification limits validation to machine-performed or clearly disclosed attendant role | Specifically, the court did not adopt a broad attendant-only construction; maintains machine-performed validation as central |
