In Re PAPST LICENSING GMBH & CO. KG LITIGATION
967 F. Supp. 2d 1
D.D.C.2013Background
- Papst Licensing sues multiple camera manufacturers in the District of Columbia for infringement of Papst Patents 6,470,399 and 6,895,449.
- Defendants move for summary judgment of noninfringement on the data transmit/receive device limitation when accused cameras operate in USB MSC mode.
- Court construes the data transmit/receive device as capable of transmitting data to a host when connected to the host via the interface device.
- Berg Declaration testifies USB MSC devices cannot transmit data from external accessories to the host when the camera is in MSC mode.
- Papst fails to raise genuine issues of material fact; expert Locke’s declarations do not create triable disputes; summary judgment granted.
- Court also denies Papst’s Rule 56(d) discovery request regarding the data transmit/receive device limitation and back-door modes.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether external accessories meet data transmit/receive device limitation | Papst | Camera Manufacturers | No; limitations not met in MSC mode |
| Whether Papst has genuine issues of material fact | Papst | Camera Manufacturers | No; Papst failed to raise triable issues |
| Doctrine of equivalents applicability | Papst | Camera Manufacturers | Inapplicable; sanctions prevent new theory |
| Court’s reconsideration of data transmit/receive device construction | Papst | Camera Manufacturers | Denied; construction upheld |
