Need a patent search? Start with a reproducible prior-art record.

Write a safe-to-share description of the problem, the result, and the features that produce it. Separate essential features from optional implementations. For each feature, list technical synonyms, older terms, industry terms, materials, components, inputs, outputs, and alternative mechanisms. Do not begin with the product name; patent documents often describe the same function in language a product team would never use.

The USPTO preliminary-search guidance begins with description terms and Cooperative Patent Classification, or CPC, categories. Use Patent Public Search to combine keywords, fields, dates, assignees, inventors, and classifications. Save every query and result count. A result list without the failed and narrowed queries cannot be reproduced or reviewed.

For each promising document, record the publication number, priority and publication dates, assignee, inventors, family members, status source, classifications, citations, and the passages or figures that caused you to keep it. Follow backward citations to older references and forward citations to later work. Search technical papers, standards, product manuals, conference material, and other non-patent literature where the field requires it.

Finish with coverage, not a verdict. State which essential features appeared together, which appeared separately, which remained unsearched, and which terminology or classification paths still need work. The USPTO expressly warns that an examiner may find material information a preliminary search did not uncover.

A general AI assistant can break an approved technical description into feature phrases, generate synonyms and alternative mechanisms, propose Boolean queries, suggest CPC terms to verify, normalize exported bibliographic data, and draft a comparison table. It is especially useful when the inventor’s vocabulary is narrower than the language used in adjacent fields.

Do not ask it to search from memory or to supply patent numbers without a live source. Models can produce convincing but nonexistent citations, collapse separate family members, misread status, or treat an abstract as if it were a legal conclusion. Give it exported text only when authorized, require a source field for every fact, reopen each patent record, and leave any unsupported cell blank.

Before describing an unpublished invention, confirm company policy, disclosure authority, and the provider’s current data terms. Anthropic’s consumer retention notice and OpenAI’s ChatGPT data-controls notice describe different product settings; neither substitutes for patent counsel’s disclosure advice or permission to share restricted technical material.

A safe sequence is to start with a sanitized feature map, ask for vocabulary, verify classifications in the official system, run the queries yourself, and return only authorized public records for clustering. Preserve the search history outside the chat so another researcher or practitioner can rerun it.

A registered patent attorney or agent can prepare and prosecute a patent application before the USPTO. Patent agents are not attorneys: the USPTO says they cannot argue patent cases in court or perform services a jurisdiction treats as practicing law, such as drafting an assignment or license where local law reserves that work to attorneys. Use an appropriately licensed patent attorney for infringement, freedom-to-operate, ownership, licensing, contracts, disputes, and broader legal opinions. The USPTO Patent Practitioner Search lets the public search registered attorneys and agents. Interview for the technical field and the exact assignment; registration alone does not show experience with your technology or the requested work.

Send the professional the approved invention disclosure, decision date, known disclosures, ownership facts, feature map, complete query history, ranked references, missing search areas, and the questions the business needs answered. Ask whether the fee covers a search, a patentability assessment, claim drafting, filing, prosecution, a freedom-to-operate opinion, an agreement, or some defined combination. Confirm that the person is licensed for every part of that scope.

Government filing fees are only one part of the decision. The current USPTO fee schedule lists a provisional filing fee of $325, $130 for a small entity, or $65 for a micro entity. A nonprovisional utility application also requires search and examination fees. Those figures do not include practitioner time, drawings, later responses, foreign filings, or maintenance.

Suppose a small manufacturer is testing a sensor clamp that measures vibration on existing equipment without drilling or rewiring. The initial language—“wireless vibration clamp”—is too narrow. The feature map separates attachment method, sensor type, power, signal processing, transmission, equipment geometry, installation constraint, and the decision the company must make before a prototype demonstration.

The search then adds terms for removable mounts, accelerometers, condition monitoring, energy harvesting, edge processing, telemetry, and adjacent CPC categories. One candidate document may show the mounting relationship; another may show the sensing and transmission path; a technical paper may describe the same installation constraint. The report records those separate findings without claiming that they establish patentability or infringement.

Counsel receives the complete trail: the sanitized and full feature maps, every query, the ranked documents, what appeared together, what appeared only in pieces, and the planned disclosure date. If the product changes, STEL can rerun the affected branches instead of starting from a forgotten keyword list.

STEL is the Fidelic patent-intelligence lead. STEL maintains feature maps, search vocabulary, classifications, query histories, ranked references, patent families, status checks, competitor watches, technical-literature records, and counsel packets. The team can inspect the source and see which question remains open in Slack.

The search universe is large and still growing. WIPO reports 3.7 million patent applications worldwide in 2024, a 4.9 percent increase, and about 3.5 million patents in force in the United States. Those global totals do not measure the difficulty of one invention search. They do show why classification paths, dates, families, citations, and non-patent sources need a reproducible record.

STEL does not interpret a claim as a legal conclusion or tell the company it is free to operate. STEL prepares the technical evidence so the appropriate patent attorney or agent can spend time on the professional work. Review the current price and trial terms, Fidelic’s systems and data boundaries, and the related VIAN’s broader portfolio function before connecting invention records.
