Yes. Non-patent literature searching is a particular strength of Crimson Insights’ patent invalidity search work. We investigate technical disclosures beyond patent publications, including scientific papers, standards, product documentation, conference materials, theses, and archived web content, depending on the technology and agreed scope.
Our searches focus on the claim limitations counsel needs to investigate and the relevant dates for the matter.
Search beyond patent publications
An important technical disclosure may appear in a research paper, a product manual, or a standards document rather than a patent. Non-patent literature can provide additional research paths where patent references leave a technical feature unresolved.
Crimson searches for the underlying technical concept, including descriptions that use terminology different from the patent’s claims.
Sources tailored to the technology
Depending on the engagement, our non-patent literature searches can include:
- Scientific and academic publications: journal articles, research papers, and technical studies.
- Conference materials: proceedings, published papers, and presentations.
- Technical standards: specifications and related standards-development materials.
- Product documentation: manuals, datasheets, technical guides, and historical product information.
- Academic research: theses, dissertations, books, and technical reports.
- Archived web materials: historical websites and publicly available technical documentation.
The source selection follows the claim issue. A communications feature may lead toward standards and conference papers, while an implemented product feature may require investigation of manuals, datasheets, and historical documentation.
Investigate historical terminology and technical context
Earlier documents may describe a function without using the language later adopted in a patent or industry standard.
Crimson investigates alternative terminology, related technical concepts, researchers, organizations, and cited publications. A relevant document can reveal additional authors, earlier work, or product information that helps expand the search.
This iterative approach allows new findings to guide further investigation.
Focus on the disclosures that matter to the claims
A publication discussing the same technology does not necessarily disclose the feature counsel is seeking.
We examine relevant passages, figures, and technical explanations against the limitations under investigation. Depending on the agreed reporting scope, findings can include observations explaining their potential relevance and claim-limitation mapping where requested.
The aim is to help counsel assess what a reference discloses and which technical gaps remain.
Investigate dates and document versions
Historical technical materials can exist in multiple editions, revisions, or archived copies. Identifying the relevant version is an important part of understanding a potential reference.
Where available, we report publication information, document identifiers, revision details, and source locations. Questions about dates or provenance should remain visible for counsel’s review rather than being treated as resolved simply because a document contains relevant technical content.
Counsel determines whether a reference meets the legal requirements applicable to the matter.
Combine NPL findings with broader prior art research
Non-patent literature can complement patent searching. A paper may identify a research group, a manual may reveal a product family, or a patent may cite an earlier technical publication.
Crimson follows these connections to develop additional search leads. NPL research can form part of a broader invalidity search or be the focus of an agreed investigation into particular technical features.
