1. Nature of Arbitrability in Patent Infringement Disputes

Patent-related arbitration typically involves three overlapping issues:

• Infringement claims arising out of license agreements
• Scope of licensed rights (field of use, territory, royalties)
• Validity challenges (often restricted in arbitration depending on jurisdiction)

Courts generally distinguish between:

• In personam rights (contractual/licensing disputes) → Arbitrable
• In rem rights (validity of patent against the world) → Often non-arbitrable or limited

2. Key Legal Principles

• Arbitration is valid if parties freely agree under a contract
• Arbitrators can interpret patent rights inter se between parties
• Courts may still retain exclusive authority over patent revocation/invalidity in rem (especially in India)
• Public policy concerns arise when arbitration affects statutory monopoly rights

3. Important Case Laws

1. Mitsubishi Motors Corp. v. Soler Chrysler-Plymouth, Inc. (1985, U.S. Supreme Court)

This is a foundational case for arbitrability of statutory claims.

• The Court held that statutory claims (including those touching intellectual property and antitrust issues) can be referred to arbitration.
• It emphasized that arbitration agreements should be enforced unless Congress explicitly excludes them.
• Established that commercial arbitration can handle complex legal disputes, including those involving patent-related commercial rights.

Significance:
Supports arbitrability of patent-related contractual disputes, including infringement claims tied to commercial agreements.

2. Henry Schein, Inc. v. Archer & White Sales, Inc. (2019, U.S. Supreme Court)

• Concerned delegation of arbitrability decisions to arbitrators.
• The Court held that if parties clearly delegate arbitrability, courts cannot override it even if claims seem “wholly groundless.”

Significance:
Strengthens party autonomy in arbitration clauses, often relevant in IP licensing disputes involving patent infringement allegations.

3. Lear, Inc. v. Adkins (1969, U.S. Supreme Court)

• Addressed patent license agreements and validity challenges.
• The Court abolished the doctrine of licensee estoppel, allowing licensees to challenge patent validity.

Significance:
Important in arbitration because it allows disputes in arbitration where a licensee may argue invalidity or non-infringement despite contractual obligations.

4. Booz Allen & Hamilton Inc. v. SBI Home Finance Ltd. (2011, Supreme Court of India)

• Laid down the distinction between rights in rem and rights in personam.
• Held that disputes involving rights in rem are not arbitrable, while rights in personam are arbitrable.

Significance:
Patent infringement claims affecting public rights (validity/registration) are generally non-arbitrable in India, but contractual infringement disputes are arbitrable.

5. Vidya Drolia v. Durga Trading Corporation (2020, Supreme Court of India)

• Reaffirmed and refined arbitrability principles.
• Introduced a four-fold test for arbitrability, including:
  • Whether the dispute relates to actions in rem
  • Whether it affects third-party rights
  • Whether it involves sovereign/public interest functions
  • Whether it is expressly non-arbitrable by statute

Significance:
Clarifies that IP disputes under contracts (like licensing and royalty disputes) are generally arbitrable, but validity challenges may not be.

6. Enercon (India) Ltd. v. Enercon GmbH (2014, Supreme Court of India)

• Involved IP licensing and arbitration clauses in a technology agreement.
• The Court emphasized pro-arbitration interpretation and minimal judicial interference.
• Upheld arbitration despite complex technical IP issues.

Significance:
Reinforces that technical IP disputes, including patent-related contractual disputes, are suitable for arbitration.

4. Practical Position in Patent Infringement Arbitration

In contractual arbitration, arbitrators typically can decide:

• Whether infringement occurred between contracting parties
• Whether royalty payments are due
• Whether licensing terms were breached
• Whether use falls within licensed scope

However, they usually cannot invalidate a patent erga omnes (against the world) unless explicitly permitted by law.

5. Key Takeaway

Patent infringement-related arbitration is primarily contract-driven, not statutory. Courts across jurisdictions increasingly support arbitration for:

• Licensing disputes
• Contractual infringement claims
• Commercial exploitation of patents

But they remain cautious about arbitration affecting public patent validity rights, especially in jurisdictions like India.
