NPE Patent Assertion

NPEs and PAEs have transformed US patent litigation: DEFINITIONS: NON-PRACTICING ENTITY (NPE): any patent holder that does not manufacture products practicing the patents; includes universities; individual inventors; failed startups; hedge funds; and dedicated licensing companies; the term is value-neutral — universities are NPEs but are generally not considered trolls; PATENT ASSERTION ENTITY (PAE): an NPE whose primary business is acquiring and asserting patents against operating companies; PAEs are what critics call 'patent trolls'; the distinction from legitimate NPEs is the PRIMARY REVENUE SOURCE being litigation/licensing rather than innovation; PATENT TROLL: pejorative term for PAEs; some apply it broadly to any NPE that demands licensing fees; others apply it only to the most abusive PAE practices; PAE BUSINESS MODEL: ACQUISITION: buy distressed patent portfolios from bankrupt companies; failed startups; or individual inventors; often at a fraction of assessed value; AGGREGATION: combine patents from multiple sources into thematic portfolios; build a claim chart for each target company; DEMAND LETTER CAMPAIGN: send demand letters to target companies asserting infringement; offer to license for $50K-$500K (less than the cost of litigation); many companies pay immediately without investigating validity; ESCALATION: if the company does not pay, file suit; PAE litigation threat is credible because PAEs have no products for counter-assertion; FAVORABLE JURISDICTIONS: historically filed in Eastern District of Texas; now Western District of Texas and District of Delaware (post TC Heartland); WHY DEMAND LETTERS WORK: litigation costs $2-10M per case; many companies pay the demanded license fee even if the patent is invalid or non-infringed; settlement is often cheaper than defense regardless of the merits; NO COUNTER-ASSERTION LEVERAGE: operating companies typically settle with other operating companies partly because of mutual patent portfolios (cross-license); NPEs have no products so operating company's patents cannot be asserted back.

Multiple reforms have attempted to curtail abusive NPE tactics: AIA INTER PARTES REVIEW (IPR): the America Invents Act (2011) created IPR, which allows anyone to challenge an issued patent at the PTAB; PAEs typically hold patents of weaker quality (older portfolios; broad claims); IPR has been highly effective: PTAB institution rate on PAE-asserted patents was historically higher than for operating company patents; approximately 80% of instituted IPR proceedings result in at least one claim being cancelled or amended; IPR is cheaper than district court ($50-200K vs. $2-10M per side in litigation); a PTAB institution decision can pressure NPEs to drop suits or settle cheaply; IPR TIMING: must file IPR petition within 1 year of being served with a complaint; VENUE REFORM — TC HEARTLAND (S.Ct. 2017): TC Heartland LLC v. Kraft Foods Group (S.Ct. 2017): patent venue is proper only where: (a) the defendant is incorporated; OR (b) the defendant has committed acts of infringement AND has a regular and established place of business; this overturned the broadly permissive pre-2017 rule that allowed NPEs to file anywhere the defendant sold products; IMPACT: Eastern District of Texas NPE filings dropped dramatically; cases concentrated in Delaware (for nationally incorporated companies) and Western District of Texas (W.D. Tex. has emerged as a major patent venue); AIA JOINDER LIMITATIONS: before AIA, NPEs could sue 100+ defendants in one case (accusing unrelated companies of infringement in a single suit = efficient extraction); AIA § 299 requires true joint parties or related transactions; NPEs must now file individual suits against each unrelated defendant; significantly increases PAE transaction costs; FEE SHIFTING — OCTANE FITNESS (S.Ct. 2014): Octane Fitness v. ICON Health (S.Ct. 2014): lowered the standard for 'exceptional case' attorney fees under 35 U.S.C. § 285; exceptional case = one that 'stands out from others with respect to the substantive strength of a party's litigating position or the manner in which the case was litigated'; fee shifting has become a real deterrent for weak PAE assertions; Highmark (S.Ct. 2014): district court fee decisions reviewed for abuse of discretion (deferential) not de novo.

NPE defense requires both legal strategy and business judgment: PRELIMINARY LEGAL ASSESSMENT: before responding, assess: patent validity (prior art; § 101; § 112); claim scope (does your product really infringe the claims?); patent ownership (chain of title; standing); NPE's litigation track record; the merits determine which defense strategy makes sense; EARLY DISMISSAL — ALICE § 101: for software and business method patents (common in NPE portfolios), file a Rule 12(b)(6) motion to dismiss on § 101 grounds; courts grant § 101 motions at the pleading stage relatively frequently for abstract idea patents; success on § 101 = case dismissed before discovery; cost: $50-200K (cheap compared to full litigation); INTER PARTES REVIEW (IPR): if you have strong prior art against key claims, file an IPR petition within 1 year of complaint service; IPR can cancel claims BEFORE trial; settlement leverage increases dramatically with a strong IPR filing; joining with other defendants (same patents asserted against multiple companies) = share IPR cost; INVALIDITY IN DISTRICT COURT: assert § 102 (novelty); § 103 (obviousness); § 112 (indefiniteness; written description; enablement) in district court in parallel with IPR; CLAIM CONSTRUCTION: narrow claim construction through Markman briefing can eliminate infringement even if claims survive invalidity; NPEs often depend on broad functional claim constructions; NON-INFRINGEMENT ARGUMENTS: element-by-element comparison against actual products; especially important for method claims (must perform all steps); EXCEPTIONAL CASE FEE MOTION: if NPE's position is objectively unreasonable, preserve fee motion; document NPE's unreasonable positions throughout litigation; motion filed after winning on the merits; VENUE CHALLENGE: if NPE filed in unfavorable venue, move to transfer under 28 U.S.C. § 1404(a) (convenience of parties and witnesses) or § 1406 (improper venue); BUSINESS DECISION — PAY OR FIGHT: for demands < $200K with weak patents, paying may be cheaper; for threats to core products or high demanded amounts, litigation is often necessary; operating company must consider: precedent for future demands (paying once often generates follow-on demands); multiple defendant situations (if others are fighting, piggyback on their IPR).

Understanding NPE sourcing reveals what patents are at risk: PAE ACQUISITION SOURCES: BANKRUPT COMPANIES: when a startup or technology company fails, its patent portfolio is often sold in bankruptcy proceedings for pennies on the dollar; PAEs are active buyers at bankruptcy auctions; classic example: Nortel Networks bankruptcy (2011) — consortium led by Apple/Microsoft/Sony paid $4.5B for 6,000 patents; PAEs bid on the same portfolios; INDIVIDUAL INVENTORS: inventors who obtained patents but lacked resources to manufacture or license; PAEs offer upfront cash (often $5K-$50K per patent) for assignments; LARGE COMPANY SPINOUTS: some large companies sell non-core patent portfolios to PAEs while obtaining back-licenses; this monetizes patents while maintaining freedom of operation; sometimes structured as NPE 'partnerships'; R&D COMPANIES WITHOUT COMMERCIALIZATION: pure research organizations that patent discoveries but cannot commercialize them; university TTOs (though universities prefer to license directly); WHAT MAKES A PATENT ATTRACTIVE TO PAEs: BROAD FUNCTIONAL CLAIMS: claims using generic functional language ('means for processing'; 'a system configured to communicate') that may read on many different implementations; large number of potential defendants = high aggregate license value; FOUNDATIONAL TECHNOLOGY: basic platform technologies (communication protocols; data formats; payment methods; UI paradigms) practiced by many companies; PROVEN CLAIM CONSTRUCTION: patents that have survived claim construction in prior litigation; AGING PATENTS: older patents (approaching expiration) that companies may not have watched closely; CROSS-INDUSTRY APPLICABILITY: patents that read on multiple industries' products (not just one vertical); WEAK PRIOR ART LANDSCAPE: patents where the closest prior art was not cited during prosecution (increasing IPR/invalidity risk that PAE can argue is limited).

Proactive IP strategy reduces NPE exposure and improves defense capability: PATENT WATCH PROGRAM: actively monitor PAE patent acquisitions and demand letter campaigns; PAE portfolios and pending suits are public records; knowing which PAEs are active in your technology space enables proactive defense; JOIN DEFENSIVE PATENT COMMUNITIES: OPEN INVENTION NETWORK (OIN): join OIN for protection in Linux/open-source technology space; LOT NETWORK (LICENSE ON TRANSFER): patent cross-license community; members share licenses when patents transfer to PAEs; if a PAE acquires a patent from a LOT member, all other LOT members receive a license; increasingly large community (Apple; Google; Salesforce; Ford; etc.); UNIFIED PATENTS: membership organization that funds IPR challenges against PAE-asserted patents in specific technology sectors; members pay fees; Unified Patents' PTAB team proactively challenges PAE patents before they are asserted; DEFENSIVE PATENT ACQUISITION: buy your own patents in technology areas where PAEs are active; a patent you own cannot be asserted against you; cross-licensing leverage increases; PRIOR ART LIBRARY: participate in prior art search databases (Article One; defensive disclosure databases); submit relevant prior art for PAE-asserted patents in your space; DATABASE OF PAE DEMAND LETTERS: track demand letters received by your organization and industry peers; if PAE sends demand letters to many companies, defendants may coordinate defense; INSURANCE: patent assertion insurance (litigation defense insurance) covers cost of defending patent suits; premiums calibrated to company's patent exposure; large technology companies often self-insure or use captive insurance structures; STRONG IP PORTFOLIO OF YOUR OWN: own key patents in your technology space; when a PAE asserts, review whether any of your patents can be asserted in defense (may not work against NPEs with no products but may support a cross-licensing negotiation if the PAE has licensed others with competing patents); LITIGATION RECORDS: maintain records of all prior art investigations done during product development (predates infringement; shows good faith; limits willfulness exposure).
