403 F.Supp.3d 571
E.D. Tex.2019Background
- Papst sued Samsung alleging infringement of claims 1 and 17 of U.S. Patent No. 6,895,449 (the ’449 patent); jury trial held Oct. 30–Nov. 6, 2018 resulting in verdict for Papst (infringement, not willful) and $5,924,374 damages.
- Multiple related IPRs against other Papst patents produced Final Written Decisions cancelling other patents; no Final Written Decision issued against the ’449 patent, and Papst kept the ’449 claims in district court against Samsung.
- Key claim constructions at issue included: “customary” (devices normally part of commercially available systems in 1997) and “simulating a virtual file system to the host” (presenting an emulated file system that does not actually exist on the interface device).
- Samsung moved post-trial for JMOL or a new trial on liability and damages and sought leave to contact jurors; Papst moved for entry of judgment; the Court heard arguments July 11, 2019.
- The Court denied Samsung’s motions for JMOL/new trial on liability and damages, denied leave to contact jurors, and denied Papst’s motion for entry of judgment without prejudice (pending resolution of Samsung’s motion for leave to amend alleging inequitable conduct).
Issues
| Issue | Plaintiff's Argument (Papst) | Defendant's Argument (Samsung) | Held |
|---|---|---|---|
| Direct infringement — "customary" signaling | Accused devices send bInterfaceClass 08h which signals mass-storage and falls within broad category of mass storage customary in 1997 | Devices identify as USB Mass Storage Class (which didn’t exist in 1997), so cannot meet “customary” limitation | Denied JMOL; jury had substantial evidence to find USB MSC falls within mass-storage category customary in 1997 |
| Direct infringement — capability to "signal regardless of DTRD" ("misidentification") | Interface signals to host it is a hard-disk-like storage regardless of attached DTRD (e.g., CMOS/mic); experts supported that interface announces "I am mass storage" | Devices truthfully comply with USB spec; they are multifunction devices (phone+storage) so not capable of misidentifying | Denied JMOL; factual dispute for jury (credibility of experts) supported infringement finding |
| Direct infringement — "simulating a virtual file system" (emulation not existing on interface) | SD card file system as presented to host emulates a hard-drive FAT (references to sectors/heads) and SD card is not part of interface device | SD card stores a real file system and when installed is "on" the device; not an emulation of a non-existent file system | Denied JMOL; jury could find presented file system emulates a hard drive and does not exist on interface device |
| Indirect infringement (intent, direct infringement by customers, substantial noninfringing uses, component) | Evidence: notice to Samsung, corporate admissions that customers are instructed to use USB Mass Storage mode and surveys/sales supporting user infringement; expert testimony on lack of substantial noninfringing uses for combination | Samsung had a good-faith, reasonable noninfringement belief; user manuals alone insufficient to prove inducement; components have substantial noninfringing uses | Denied JMOL; issues of knowledge, intent, customer infringement and noninfringing uses were factual for jury and supported by record |
| Invalidity — anticipation/obviousness (Kawaguchi/Schmidt/Murata & Coolpix) | Samsung failed to prove invalidity by clear and convincing evidence; expert testimony was impeached and motivation/expectation-of-success not established | Prior art combinations and Coolpix anticipate/obvious over claims; Papst failed to rebut (no rebuttal expert) | Denied JMOL; reasonable jury could reject Samsung’s clear-and-convincing showing given credibility and motive-to-combine issues |
| Damages — reasonable royalty methodologies (income and market approaches) | Mr. Benoit’s income and market methods apportion and rely on surveys/licenses; properly apportioned and admissible | Benoit misapplied EMV rule, relied on unreliable surveys, double-counted benefits, and used noncomparable licenses; hypothetical negotiation date disputed | Denied JMOL and new trial; Court finds Benoit’s methods admissible and supported by substantial evidence; factual weight for jury |
| Damages — hypothetical negotiation date & verdict form | Papst used date tied to actual accused sales; expert relied on appropriate date | Samsung sought alternate earlier date (2005) based on products never asserted; requested lump-sum/ongoing royalty instruction | Denied new trial/JMOL; Court properly struck opinions tied to unaccused products and verdict form was acceptable |
| Motion to contact jurors | N/A | Samsung requested leave to interview jurors for feedback | Denied — juror privacy and administration interests outweigh benefit |
