Professional search and analysis for inventors, startups, and overseas applicants who need to understand patentability risk before drafting, filing, design-around planning, or post-grant strategy.
ZYL Law Firm's proprietary patent prior art search workflow is designed for U.S. patent work, not generic web research. It combines professional patent database searching, structured keyword expansion, common-law style public-disclosure review, and U.S. patent practitioner analysis to identify references that may affect novelty, obviousness, design patent scope, IDS strategy, and claim drafting.
The system is built around a practical question: what should change before the application is drafted or the strategy is chosen?
The workflow starts with professional patent search sources including Google Patents, USPTO data, Patent Public Search workflows, and Espacenet/EPO coverage where available. Search terms are expanded across technical features, functions, products, use environments, design features, synonyms, and alternative implementations so the review does not depend on one narrow keyword.
Patentability can be affected by more than issued patents and published applications. The system includes a public-disclosure layer for product pages, manuals, datasheets, standards, papers, open-source repositories, videos, reviews, launch pages, forums, blogs, and archived web pages. These sources are separated from formal patent references and reviewed for possible 102/103 relevance, drafting implications, and evidence-preservation needs.
For utility inventions, the report maps proposed technical features against the closest disclosures and flags possible novelty, obviousness, 101 utility, and 112 support issues. For design matters, the system focuses on visual reference tables, article similarity, visible design features, drawing strategy, and the limits of automated image-based screening.
The final deliverable is a structured prior-art and drafting-strategy report, not a raw hit list. It covers the search scope, keyword matrix, database status, key references, public-disclosure leads, patentability observations, preliminary FTO flags, claim fallback levels, specification support needs, drawing strategy, IDS candidates, and recommended next search or drafting steps.
This workflow gives clients an earlier, clearer view of the patent landscape before major drafting or filing costs are incurred. It is especially useful for utility application drafting, design patent screening, PCT or foreign-to-U.S. filings, Office Action strategy, product design-around planning, and post-grant invalidity research.
