Patent Research
A research-focused patent skill (not legal filing). Covers prior-art search, IP landscape mapping, claim analysis, freedom-to-operate, and patentability. For formal patent prosecution, work with a licensed patent attorney.
When to use this skill
- Conducting a prior-art search before filing a provisional patent
- Mapping the IP landscape in a technology area
- Evaluating the patentability of an invention
- Assessing freedom-to-operate before launching a product
- Tracking competitive patent activity in a market
- Preparing a patent strategy for a startup or R&D group
Inputs the advisor expects
- Invention description (problem, solution, novelty)
- Technology area + relevant CPC/IPC classifications
- Target jurisdictions (US, EU, JP, CN — IP is jurisdictional)
- Existing prior art known (key references)
- Competitor list
- Timeline pressure (filing deadline, product launch)
Clarify First
Before running the analysis, confirm these inputs. If any is unknown or vague, ASK — do not assume:
- [ ] Analysis type (prior-art search, patentability, FTO, or landscape) — these are different deliverables with different methods and outputs
- [ ] Invention description (problem, solution, novelty) — drives the claims and search classifications
- [ ] Target jurisdictions (US, EU, JP, CN) — IP is jurisdictional; changes FTO scope and filing strategy
- [ ] Technology area + CPC/IPC classifications — drives a search beyond keywords (which misses synonyms/translations)
Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.
Workflows
Workflow 1 — Plan a prior-art search
- Define invention claims (key novel features).
- Identify search classifications (CPC / IPC) + keywords.
- Run
prior_art_search_planner.pyto produce a search plan. - Execute on USPTO / EPO / Espacenet / Google Patents / WIPO.
python3 patent/scripts/prior_art_search_planner.py \
--input invention.json --format markdown
Workflow 2 — Map the IP landscape
- Capture identified patents (yours, competitors', adjacent).
- Run
claim_landscape_mapper.pyto cluster by claim type, owner, technology subarea, recency; surface white space + crowded areas.
python3 patent/scripts/claim_landscape_mapper.py \
--input patents.json --format markdown
Workflow 3 — Score patentability of an invention
- Capture invention + closest prior art.
- Run
patentability_scorer.pyto rate novelty, non-obviousness, utility, subject matter eligibility.
python3 patent/scripts/patentability_scorer.py \
--input patentability.json --format markdown
Decision frameworks
The three patentability criteria (US baseline)
- Novelty (35 USC §102): not previously disclosed
- Non-obviousness (35 USC §103): not obvious to person skilled in the art
- Utility (35 USC §101): useful, with practical application
Plus:
- Subject matter eligibility (§101): not abstract idea, not law of nature
- Enablement (§112): described well enough to be made by skilled artisan
- Definiteness (§112): claims clearly distinguish
Prior-art categories
- Patents (issued + published applications)
- Non-patent literature (papers, conference, dissertations, technical reports)
- Commercial products (sold publicly before filing)
- Public disclosures (talks, demos, blog posts — yes, including your own > 1 year prior)
- Sales activity (offers for sale, even pre-launch)
Inventors often miss non-patent prior art; this is where searches break.
Freedom-to-operate (FTO)
Different from patentability. FTO asks: can I commercialize without infringing someone else's patent?
- Patentability ≠ FTO (your patent could still infringe another)
- FTO is jurisdiction-specific
- Active patents only (not expired); typically 20 years from filing
- Patent attorney involvement essential for formal opinion
IP strategy by stage
- Pre-seed: capture inventions; consider provisional filings; don't over-file
- Seed/Series A: strategic provisionals; key utility filings
- Series B+: PCT international; continuations to maintain pendency
- Mature: portfolio management; licensing; enforcement
Common engagements
"We have a new algorithm. Should we patent?"
- Subject matter eligibility check (§101 — algorithms are tricky)
- Prior art search (someone has probably published)
- Strategic value (does patent enable / defend a business position?)
- Cost-benefit ($5-25K provisional; $30-100K full prosecution)
- Often answer: keep as trade secret, not patent
"Run an FTO before our launch"
- Identify candidate blocking patents (search + competitor review)
- For each: review claims; assess infringement risk
- Identify mitigations: design-around, license, abandon, challenge
- Get formal opinion from patent counsel (insurance against willful infringement)
"Map the patent landscape in our space"
- Identify key players (companies + universities)
- Search by classification + keyword
- Cluster: by company, by sub-technology, by year
- Surface white space (uncovered areas) + crowded zones
- Strategy implications (where to play, where to design-around)
Anti-patterns to avoid
- Searching only keywords (no classification). Misses translations + synonyms.
- Searching only USPTO. EPO + WIPO + JP have unique art.
- Searching only patents. Non-patent prior art is huge.
- Public disclosure before filing. Loses patentability outside US (1-year grace in US only).
- Filing without prior-art search. Reviewer finds it; patent invalid.
- No FTO before product launch. Surprise injunctions.
- Patenting everything. $30K per patent adds up; portfolio bloat distracts.
- Filing without commercial strategy. Patents are means, not ends.
