Patent ownership disputes often arise when companies fail to explicitly secure rights to inventions created by employees or contractors. Missteps in drafting invention assignment agreements can lead to significant litigation risks, as demonstrated by recent case law.

Key Case Law Insights

1. Whitewater West Industries Ltd. v. Alleshouse (2020)

• Issue: The Federal Circuit invalidated a provision requiring post-employment assignment of inventions under California law.

• Implication: California’s strong public policy against non-compete agreements limits the enforceability of overly broad invention assignment clauses. Employers must ensure compliance with state-specific laws when drafting agreements.

2. Core Optical Technologies, LLC v. Nokia Corp. (2024)

• Issue: The Federal Circuit vacated a lower court ruling that an invention created by an employee belonged to their former employer.

• Implication: Ambiguities in employment agreements regarding invention ownership can result in costly litigation and loss of patent rights. Employers must clearly define ownership terms during employment and after termination.

3. Bio-Rad Laboratories, Inc. v. ITC (2021)

• The Federal Circuit ruled that failure to secure proper assignment documentation from inventors jeopardized enforcement of patents during litigation.

4. Siemens Mobility, Inc. v. Westinghouse Air Brake Technologies Corp. (2022)

• A lack of explicit assignment agreements led to disputes over patent ownership, weakening the employer’s enforcement position.

5. Apple Inc. v. Corephotonics, Ltd. (2023)

• Disputes arose because inventor assignments were not properly recorded, undermining Apple’s ability to assert its patents.

 

Pitfalls in Structuring Patent Assignment Agreements

1. Ambiguity in Ownership Clauses

• Agreements often fail to distinguish between inventions made:

  • Before employment.

  • During employment but unrelated to job duties.

  • After employment but using company resources.

• Courts scrutinize these distinctions, especially in jurisdictions like California that favor employee rights.

2. Post-Employment Inventions

• As seen in Whitewater West Industries, post-employment assignment clauses are vulnerable under state laws prohibiting restraints on trade.

3. Lack of Proper Documentation

• Failure to execute and record assignments promptly can result in disputes over patent ownership and enforcement challenges.

4. Contractor Agreements

• Independent contractors are not automatically obligated to assign inventions unless explicitly stated in their contracts.

 

Best Practices for Structuring Agreements

1. Drafting Clear Invention Assignment Clauses

• Use language such as “hereby assigns” rather than “agrees to assign” to ensure immediate transfer of rights upon invention creation.

• Define the scope of inventions covered (e.g., those related to the company’s business or developed using company resources).

2. State-Specific Compliance

• Tailor agreements to comply with local laws, particularly in states like California with restrictive policies on employment-related IP assignments.

3. Contractor Agreements

• Ensure independent contractor agreements include explicit IP assignment provisions covering all deliverables.

4. Confidentiality and Non-Disclosure

• Include robust confidentiality clauses to protect trade secrets and other proprietary information.

 

Proactive Portfolio Management with PatenTrack

PatenTrack is designed to identify gaps in patent portfolios by tracking assignment records and ensuring proper documentation is filed with the USPTO:

• Detect missing or improperly executed assignments.

• Flag potential disputes early.

• Strengthen enforceability during litigation by maintaining a clean chain of title.

 

Implications for Patent Prosecution and Litigation

1. Patent Prosecution

• Improper or delayed assignments can lead to standing issues during prosecution, potentially invalidating patents if ownership is disputed.

2. Litigation Risks

• Courts may dismiss infringement claims if ownership is unclear or contested due to poorly structured agreements.

• As seen in cases like Core Optical Technologies, lack of clarity can result in protracted legal battles and weakened enforcement positions.

 

To mitigate risks associated with non-explicit patent assignments, companies must adopt proactive strategies:

1. Draft clear and enforceable invention assignment agreements tailored to state laws.

2. Regularly audit patent portfolios using tools like PatenTrack.

3. Train legal counsel on best practices for securing IP rights from employees and contractors.

By addressing these pitfalls, companies can safeguard their intellectual property and avoid costly litigation over patent ownership disputes.
