Aspex Eyewear, Inc. v. Zenni Optical Inc.
713 F.3d 1377
Fed. Cir.2013Background
- Aspex sued Zenni for infringement of three magnetic clip-on eyewear patents and the district court applied collateral estoppel from an earlier Altair litigation.
- Altair involved same patents and included claim construction and summary judgment of non-infringement; Altair III affirmed non-infringement for ’811 and ’896 and remanded on ’054.
- Federal Circuit held that ‘retaining mechanisms’ requires rims, leading to non-infringement against Altair’s rimless sunglasses.
- Zenni’s accused eyewear is rimless and substantially identical to Altair’s rimless product, supporting estoppel.
- Aspex argues new claim terms and new asserted claims negate estoppel; Zenni argues same infringement issues and products are identical, preserving estoppel.
Issues

|---|---|---|---|
| Does collateral estoppel apply to Zenni case? | Aspex argues issues differ; new terms and claims defeated prior estoppel. | Zenni contends same infringement issue and products are identical, so estoppel applies. | Yes; collateral estoppel applies. |
| Are the infringement issues identical to those decided in Altair? | Terms like primary/auxiliary frame not litigated previously; could yield different construction. | Infringement issues are the same; material product similarity ensures identical issues. | Yes; infringement issues are identical. |
| Was Aspex accorded a full and fair opportunity to litigate the asserted claims? | New claim terms and expanded claim set prevented full litigation. | Aspex had full and fair opportunity; issue-focused, not claim-count-focused. | Yes; full and fair opportunity existed. |
