The invalidation of two claims on indefiniteness is a modest positive for American Airlines, but the case survives on multiple patents and will proceed toward trial or settlement. Monitor for summary judgment motions and trial scheduling — the next material event will be a dispositive ruling or settlement. The Eastern District of Texas is a plaintiff-friendly venue, so settlement pressure remains despite the partial win.

Executive Summary
The Eastern District of Texas issued a Markman claim construction order in Intellectual Ventures' patent infringement case against American Airlines. The court adopted constructions for 16 disputed terms across five patents, finding two terms indefinite ('appropriate persistent mapping' and 'at an operational level') — a partial win for American Airlines that narrows the scope of asserted claims. The case remains active with no damages awarded or injunction issued at this stage, making this an interlocutory probability shifter rather than a final outcome.
Court Ruling Details
Key Facts
- Court found 'appropriate persistent mapping' indefinite — claim 1 and 15 of '282 Patent invalidated
- Court found 'at an operational level' indefinite — claim 26 of '282 Patent invalidated
- Court rejected American's indefiniteness challenges on 'high performance computing cluster', 'operational and connectivity problems', 'hardware and software problems', 'the modifying', and 'time interval'
- Court adopted American's construction for 'low-level driver' (driver that operates below the file system)
- Court adopted constructions for 'communications are isolated' requiring gateway-based separation
- No damages awarded; no injunction issued; case proceeds to trial on surviving claims
- This is the second claim construction order in the case — first was issued February 19, 2026
Financial Impact
No monetary damages awarded or pleaded amount stated in the opinion. Two claims found indefinite reduces potential exposure but case continues on remaining claims across five patents.
Risk Factors
- Remaining claims across five patents still in suit — potential for adverse jury verdict or injunction
- Eastern District of Texas historically plaintiff-friendly — trial risk remains material
- Appeal of indefiniteness rulings by Intellectual Ventures could restore invalidated claims
- No damages cap or settlement range disclosed — financial exposure remains uncertain
