Case Overview
The Parties
⚖️ Plaintiff
Wildcat Licensing WI, LLC is a patent assertion entity (PAE) operating in the intellectual property licensing space. PAEs typically acquire patents and assert them against companies whose commercial products they allege infringe those claims.
🛡️ Defendant
Jaguar Land Rover Limited and its U.S. commercial arm, Jaguar Land Rover North America, LLC, represent a combined automotive group responsible for premium vehicle lines globally.
Patents at Issue
The asserted patent — USRE047220E (corrected application number US15/425946) — is a reissue patent, meaning it was originally granted, then reissued by the USPTO to correct errors or broaden/narrow claims. Reissue patents carry distinct legal considerations, particularly around intervening rights, which can limit damages exposure for accused infringers.

The Verdict & Legal Analysis
Outcome
The case was resolved via **stipulated dismissal with prejudice** pursuant to **Federal Rule of Civil Procedure 41(a)(1)(A)(ii)**. Under this mechanism, all claims asserted by Wildcat Licensing WI against Jaguar Land Rover are permanently dismissed, and each party bears its own attorneys’ fees, costs, and expenses. This outcome signifies that Wildcat Licensing WI is permanently barred from re-filing the same infringement claims against these defendants on the same patent.
Key Legal Issues
The case was classified as a standard patent infringement action, with the asserted patent being a reissue patent. This introduced specific legal complexity:
Intervening Rights Doctrine: Under 35 U.S.C. § 252, when a patent is reissued with amended or broadened claims, accused infringers may invoke *absolute intervening rights* (protecting products made or used before the reissue date) or *equitable intervening rights* (protecting continued investment in infringing activities). Jaguar Land Rover’s defense team would have evaluated this doctrine carefully given JLR’s substantial commercial operations predating or concurrent with the reissue.
Breadth of Accused Products: Wildcat’s decision to accuse an extensive array of vehicle components—from transmissions and chassis to door panels and seating—may have complicated infringement proof requirements, creating significant evidentiary burden.

The asserted patent was USRE047220E (reissue patent, corrected application US15/425946), covering automotive transmission technology.
The parties filed a joint stipulation of dismissal under FRCP Rule 41, agreeing to dismiss all claims with prejudice, with each party bearing its own costs. No public damages award or licensing terms were disclosed.
It underscores that reissue patent assertions against large automotive OEMs face intervening rights defenses and sustained litigation resistance, making early-stage licensing resolution strategically preferable for patent assertion entities.
