In an era defined by accelerating technological change, Patent Litigation stands at the crossroads of innovation and corporate competition. Far from being a peripheral legal skirmish, it’s a central business strategy—driving market control, shaping patent strategies in tech companies, and serving as a key indicator of leadership in intellectual property as a business asset.
The Role of Patents in Market Dominance
Strategic patent portfolios are powerful tools. Firms leverage them to deter competitors, secure exclusive market access, and generate licensing income through licensing and patent monetization. In fast-moving sectors—such as AI and telecommunications—possessing Standard Essential Patents (SEPs) can yield outsized influence over industry standards, positioning patent holders as gatekeepers to market entry. This fuels cross-border IP litigation and drives high-stakes patent infringement lawsuits.
The Strategic Value of Patent Portfolios
Why do companies engage in patent litigation:
Protecting innovation: A company spends millions on R&D. If a rival copies it, litigation ensures they can block them and keep their market share.
Earning money through licensing: Sometimes the goal is not to ban a competitor but to force them to pay licensing fees.
Market control: Having strong patents (and being ready to enforce them) can scare off competitors and help the company dominate a sector.
Defending against claims: If sued, companies litigate to prove that the patent against them is invalid or that they didn’t infringe.
Anatomy of a Corporate Patent Dispute
A corporate patent dispute typically begins when a company alleges infringement of its patent rights by a competitor. The process unfolds in distinct stages: assertion (sending cease-and-desist letters or filing a complaint), defense (the accused party challenges the patent’s validity or denies infringement), and discovery (both sides exchange technical and financial evidence). High-stakes disputes frequently involve requests for injunctions to block product sales, claims for damages to recover lost profits, and counterclaims that expand the scope of the litigation. Because modern business is global, these cases often spread across multiple jurisdictions, requiring coordination of legal, technical, and commercial strategies. Ultimately, most disputes conclude not with a dramatic trial verdict, but through settlement, licensing agreements, or arbitration, reflecting that the true objective is business leverage, not legal victory.
Defensive vs Offensive Patenting
Companies adopt both offensive and defensive patenting strategies. Offensive approaches include enforcing patents to block rivals; defensive strategies focus on building a broad patent portfolio to dissuade litigation or to negotiate favorable cross-licenses. A hybrid approach enables firms to weaponize their IP while maintaining flexibility in negotiation and R&D.
| Aspect | Defensive Patenting | Offensive Patenting |
| Goal | Protect existing innovations, operations, and freedom to operate | Maximize financial and competitive value by using patents actively |
| Strategy | File patents to prevent competitors from patenting the same/similar ideas; acts as a “security blanket” | Pursue patents on core innovations (even beyond current products) to create leverage in licensing or litigation |
| How it Works | Creates obstacles for competitors, making it harder for them to patent or sue | 1. Licensing: Generate revenue by licensing technology 2. Litigation: Sue competitors who infringe 3. Barriers: Build strong IP walls to block market entry |
| Costs | Generally, less expensive; focus on securing ability to use inventions, not enforcing them | More costly and resource-intensive; requires filing, maintaining, and enforcing large portfolios |
| Example | Filing patents on incremental product features to stop rivals from patenting and suing | Filing patents on breakthrough technologies (even pre-commercialization) for future licensing or negotiations |
Licensing and Patent Monetization
Licensing is a dual-edged sword—it can generate revenue streams, reinforce partnerships, and solidify market positions. But when licensing involves FRAND (Fair, Reasonable, And Non-Discriminatory) obligations, as with SEPs, conflicts often spur litigation. The Lenovo–Ericsson settlement in 2025 rose from just such FRAND disputes, covering 4G/5G technologies across multiple jurisdictions—with arbitration employed to set binding royalty terms.

Evolving Legal Processes & Global Patent Wars
- PERA 2025 (Patent Eligibility Restoration Act)1
In the U.S., PERA 2025 (Patent Eligibility Restoration Act) aims to recalibrate patentable subject matter to its pre-2012-2014 baseline—restoring eligibility for life sciences and technological innovations while limiting abstract or natural ideas. The bill aims to reduce vague, judge-made patent exceptions by defining specific statutory exclusions, providing a more predictable and stable patent system to encourage innovation in technology-based fields.
- USPTO Rule Overhauls
Inter Partes Review (IPR) Changes2: A major procedural shift occurred on March 26, 2025. Now, petitions are reviewed in two phases: At first, a panel may deny based on policy or economic grounds (discretionary denial), then, if not denied, another panel addresses the merits. This change imposes stricter deadlines and procedural demands—requiring separate briefs—favoring efficiency over aggressive challenges.
AAPA Limitation in IPRs3: As of September 1, 2025, the USPTO banned reliance on Applicant-Admitted Prior Art (AAPA) in IPR petitions entirely—tightening the evidentiary standards and making it harder to challenge patents using admissions by the inventors themselves. Companies must now bring in stronger outside evidence (like published research, earlier patents, or public use).
Motions to Amend Rule4: Since September 18, 2024, patent owners can seek preliminary guidance from the PTAB on amendments to the claims—resulting in a 41% increase in successful claim amendments.
- Special 301 Report5
The U.S. renewed its Special 301 Report in April 2025, raising concerns over enforcement gaps in countries such as Indonesia and Vietnam—particularly concerning pharmaceutical patent protections.
Key Lessons from Global Patent Disputes
- Strategic Patents as Business Tools:
Patent portfolios are not just legal shields—they drive mergers, investment, and market leadership. - Procedural Nuance Matters:
Changes in IPR rules, like bifurcated reviews and AAPA restrictions, significantly affect litigation strategies. - Global Forums Influence Strategy:
Harmonised venues (like the UPC) or divergent rules across regions (EU withdrawal of SEP regulation) require nimble, jurisdiction-specific strategies. - Policy and Enforcement Shape Markets:
Regulatory actions, from FTC scrutiny to tariff-based investigations, reshape established patent defense models. - Licensing Sets the Tone of Innovation:
Settlements like Lenovo–Ericsson illustrate how complex, cross-border patent disputes are increasingly resolved via licensing and arbitration rather than courtroom battles.
Patent Litigation in India: Pharma Dominance, SEP Battles, and New Rules
In India, patent litigation has become more dynamic in both pharmaceutical and technology sectors. One of the recent important rulings is Ericsson vs Lava (2024)6, where the Delhi High Court found that 7 of 8 SEPs related to 2G/3G were valid and infringed, and assessed fair royalties under FRAND, dealing also with issues like royalty stacking and exhaustion. Moreover, a notable biosimilar-patent case: ER Squibb & Sons v. Zydus Lifesciences (2025), where the court granted an interim injunction against Zydus for its planned biosimilar version of nivolumab (Opdivo), highlighting how early enforcement actions can be highly effective.
In 2025, a Draft Patents (Amendment) Rules, 2025 has been proposed by the government. This draft introduces more electronic forms, civil adjudication for things like improper use of “Patent Office” term, higher penalties for false or missing information under certain sections, and simplified online complaint/appeal procedures.
Final Thoughts
Patent Litigation is more than legal adversity—it is a critical business instrument. From patent claim amendments to sweeping legislative reform (like PERA 2025), evolving USPTO procedures, international fee realignments, and fragmented enforcement across regions, it shapes every stage of the innovation lifecycle.
For decision-makers and experts, navigating this terrain requires not just legal acumen but strategic insight—aligning IP policy, litigation readiness, licensing strategy, and global positioning to safeguard innovation and sustain market leadership.
