FAQ
Frequently asked questions.
What is Prior Art?+
Prior art is any evidence — patents, publications, products, or public disclosures — that existed before your invention's filing date and could affect its novelty or inventive step.
Why is prior art important?+
It determines patentability, shapes claim scope, reduces prosecution risk, and defends against future invalidity challenges.
How long does a search take?+
Standard turnaround is 72 hours. Expedited 24-hour delivery is available for most search types.
Which databases are searched?+
USPTO, EPO, WIPO, JPO, KIPO, CNIPA, Indian Patent Office, Espacenet, Google Patents, The Lens, and NPL sources such as IEEE, ACM, ScienceDirect, Springer, and PubMed.
Can I search unpublished patents?+
Unpublished applications are confidential by law, but we surface every published application, granted patent, and public disclosure globally.
Can this search reduce office actions?+
Yes. Identifying the closest prior art before drafting lets your attorney craft claims that avoid known references, materially reducing §102/§103 rejections.
Do you provide claim mapping?+
Yes. Our reports include element-by-element claim charts for the most relevant references.
How confidential is my invention?+
Every engagement is under NDA. We are SOC 2 and ISO 27001 aligned with private-tenancy AI options and privileged workflows.
