Yes. Crimson Insights can undertake a further search for prior art that earlier searches may have missed. We investigate alternative terminology, additional sources, citation trails, and historical technical disclosures, focusing on the claim limitations that remain unresolved.
A further search cannot guarantee a particular finding. Its value lies in identifying and pursuing relevant research paths beyond those already explored.
Search beyond the original terminology
An earlier publication may describe a technical feature using language different from the patent’s claims. Terminology can vary across industries, countries, and periods of technological development.
Crimson investigates synonyms, historical terminology, related technical concepts, and alternative descriptions of how a feature works. We combine these with classifications and other search strategies to look beyond documents that repeat the patent’s wording.
Investigate non-patent literature
Relevant disclosures are not confined to patents and published applications. Depending on the technology and agreed scope, we search sources such as:
- Scientific papers and conference proceedings.
- Technical standards and related publications.
- Product manuals, datasheets, and technical documentation.
- Books, theses, and technical reports.
- Archived websites and historical product information.
These sources can reveal how a technology was described, researched, or implemented before it appeared in the patent literature. Identified material still needs to be evaluated for its technical relevance and applicable dates.
Follow citations and related technical work
A promising reference can provide more than a single disclosure. Its citations, authors, inventors, assignees, and related publications may point toward earlier work.
Crimson follows these leads to expand the investigation. Patent families, backward and forward citations, related research, and historical terminology can help identify documents that an initial keyword search did not surface.
Explore international patent literature
Earlier disclosures may exist in patent collections outside the jurisdictions emphasized by a previous search.
Depending on the subject matter and scope, Crimson searches international patent literature, including relevant Asian collections. Patent-family information, classifications, citations, and machine-translated text can help identify potentially relevant foreign-language references.
Focus on the missing claim limitations
A document can be technically similar to an invention without addressing the limitation counsel needs to investigate.
Crimson’s claim-focused approach directs attention to those unresolved features. Known references help establish what has already been found and where further research may be useful. We develop search concepts around the remaining technical issue rather than simply repeating a broad search for the patent’s general subject.
Refine the investigation as new leads emerge
Searching for difficult prior art is an iterative process. A newly identified document may reveal a different technical term, an earlier product, a relevant standard, or another organization working on the same problem.
We use those findings to refine subsequent searches. The investigation develops as the evidence develops, allowing promising paths to receive further attention.
Make the findings useful for review
Depending on the agreed deliverables, Crimson can report relevant references, passages, figures, date information, and observations explaining their potential relevance. Claim-limitation mapping is available where requested.
The distinction between finding a promising reference and establishing its legal significance remains important. Our research supports counsel’s assessment of the disclosures, dates, and remaining gaps.
Discuss the prior art your search has not yet found
If an earlier search has left important claim limitations unresolved, share the patent, selected claims, known references, and the technical features requiring further investigation.
Crimson offers fixed-fee patent invalidity search engagements, with fees determined by the number of claims and the technology involved.
