Vasudevan Software, Inc. v. Tibco Software, Inc.
782 F.3d 671
Fed. Cir.2015Background
- VSi sued MicroStrategy and TIBCO asserting claims from four patents directed to OLAP cubes that access and process "live" data from multiple incompatible/databases without staging in a warehouse. Defendants denied infringement and challenged validity.
- Central claim term dispute: meaning of "disparate databases" (VSi: "incompatible databases having different schemas"; defendants: absence of compatible keys or record identifier/ID columns of similar value or format).
- District court relied on prosecution-history remarks and construed "disparate databases" conjunctively to require absence of compatible keys and absence of record ID columns of similar value and format; it clarified that "incompatible databases of different types" is treated the same and parties stipulated to non-infringement.
- District court granted summary judgment of invalidity: against MicroStrategy for lack of enablement; against TIBCO for lack of enablement and written description. VSi appealed both constructions and invalidity rulings.
- Federal Circuit affirmed the claim constructions and the non-infringement judgment, but reversed the summary judgments of invalidity (written description and enablement), finding genuine disputes of material fact and remanded.
Issues
| Issue | VSi's Argument | Defendants' Argument | Held |
|---|---|---|---|
| Proper construction of "disparate databases" | Means "incompatible databases having different schemas" (plain meaning) | Prosecution-history definition controls: databases lacking compatible keys and record ID columns of similar value and format | Affirmed district court: prosecution history definitional; conjunctive reading required (absence of all listed characteristics) |
| Whether "incompatible databases of different types" differs from "disparate databases" | Should be broader or separately construed | Should be construed same as "disparate databases"; VSi previously treated them as same | Treated as same (waiver); district court's treatment affirmed |
| Written description support for asserted claims (TIBCO) | Specification and originally filed claims describe accessing "incompatible databases" and disclose means (e.g., serialized files/correlation parameters) — expert supports possession | Specification only states result, lacks working example; screenshots show software that couldn’t access disparate databases; expert testimony is conclusory | Reversed summary judgment: genuine factual dispute exists (expert pointed to specific spec passages), so written-description invalidity not established on summary judgment |
| Enablement of asserted claims (MicroStrategy and TIBCO) | Specification and expert testimony provide sufficient guidance; inventor’s later commercialization time not dispositive | Inventor lacked working example at filing; long development time, prior failures, and broad claims require undue experimentation | Reversed summary judgment: Wands factors create genuine disputes of material fact (time to commercialize not dispositive; expert raised non-trivial enabling guidance) |
