Protect software work through strategic patent filings and defensive disclosure.

Core Strategies

1. Provisional Patent Application (PPA)

  • •Cost: ~$320 (micro entity)
  • •Duration: 12 months to file full patent
  • •Benefit: Establishes priority date, "Patent Pending" status
  • •Use case: Novel algorithms, architectures, methods in your repos

2. Defensive Publication (Open Source)

  • •Cost: Free (GitHub commits as prior art)
  • •Effect: Prevents others from patenting your work
  • •Platforms: arXiv, Zenodo, GitHub with clear timestamps
  • •Use case: When you want to keep it open, not exclusive

3. Trade Secret + Patent Hybrid (Proprietary)

  • •Trade secret: Keep implementation details private
  • •Patent: Protect the method/system publicly
  • •Use case: Proprietary software where you want both exclusivity and enforcement rights

4. Provisional → PCT → National Phase

  • •Timeline: 12mo (provisional) → 30mo (PCT) → national filings
  • •Cost: Escalates significantly at each phase
  • •Use case: International protection for high-value innovations

USPTO Requirements (2025)

Micro Entity Status

  • •< 4 prior patents
  • •< 3x median household income (~$250k)
  • •80% fee reduction

Claims Structure

  • •Independent claims: Broadest protection
  • •Dependent claims: Fallback positions
  • •Method claims: Process/algorithm protection
  • •System claims: Implementation protection

Workflow by Context

Public Repos

code
1. Identify patentable subject matter
2. File provisional BEFORE public commit (or within 1-year grace)
3. Document: problem, solution, advantages, embodiments
4. Continue development openly
5. Within 12 months: decide full patent vs abandon

Private/Proprietary

code
1. Identify patentable subject matter
2. Assess: patent vs trade secret vs both
3. File provisional to lock priority date
4. Keep implementation as trade secret if desired
5. Patent claims cover method/system, not code

Prior Art Search

Before filing, search:

  • •USPTO Patent Full-Text (patents.google.com)
  • •arXiv, Semantic Scholar (academic prior art)
  • •GitHub code search (implementation prior art)

Key Dates (2025 USPTO Changes)

  • •IPR tightening: Harder to challenge granted patents
  • •Fee increases: File before rate changes
  • •AI inventorship: Still requires human inventor

SF Bay Area IP Firms

  • •Fenwick & West (tech-focused)
  • •Wilson Sonsini (startup-friendly)
  • •Knobbe Martens (patent prosecution)
  • •Fish & Richardson (litigation strength)
