Prior Art Search Attorney

Before you invest in a patent, find out what already exists. A professional prior art search shows whether your invention is likely patentable and where the claims should focus.

What’s Included

  • Patentability searches — Searches of US and international patents and published applications, plus non-patent literature where relevant.
  • Attorney analysis — Not just a list of references: a clear opinion on what they mean for your invention.
  • Claim-focus recommendations — Guidance on which features are most likely to be new and non-obvious.
  • Landscape and competitor searches — A view of who else is patenting in your space and where the white space is.

How It Works

  1. Understand the inventionWe identify the key features that make your invention different.
  2. SearchWe search patent and non-patent sources using classification and keyword strategies.
  3. AnalyzeWe compare the closest references to your invention.
  4. AdviseYou get a plain-language recommendation on whether and how to proceed.

Frequently Asked Questions

What is prior art?

Prior art is any evidence that your invention was already known, including earlier patents, published applications, articles, products and public demonstrations.

Is a prior art search required to file a patent?

No, but it is strongly recommended. It helps you avoid spending money on an application that is unlikely to be granted and helps focus the claims on what is truly new.

Can I just search Google Patents myself?

A self-search is a good first step, but professional searches use classification codes and non-patent sources, and include legal analysis of what the results mean.

How long does a prior art search take?

Typically one to two weeks, depending on the technology.

Does a clean search guarantee a patent?

No search is exhaustive, and the examiner may find other references. A good search significantly reduces the risk of surprises.
