PATENTS

Read a patent's claims and description with every answer tied to the text

A patent is two documents in one: claims written in dense legal language that define what is protected, and a long description that explains the invention in many variations. Put the patent PDF in a Search+ workspace, ask what the claims cover, how a feature is described or which earlier documents are cited, and open the cited passage to read the patent's exact wording.

How to read a patent with Search+

Upload the patent and related publications
Add the granted patent or published application. If you are tracking a family, add the related publications too, since claims often change between the application and the grant. Older patents that only exist as scans can be added as well.
State what you are looking for
Use Workspace Context, for example "I am mapping what the independent claims require; quote claim language exactly and name the claim number". Search+ applies it to every question.
Ask about claims, then the description
Ask what each independent claim requires, then where the description supports a feature. Open the citations to read the claim and the passage in the description side by side.

What reading a patent needs

The claims define the protection

The legal scope of a patent is set by its claims, not by its title, abstract or drawings. Read the claims first, and treat the abstract as a summary only.

Independent and dependent claims

Independent claims stand on their own; dependent claims refer back to another claim and add limitations. The broadest protection is in the independent claims.

The description supports the claims

The detailed description and its embodiments explain how the invention can be made and used, and are often used to interpret what claim terms mean.

Applications and grants differ

A published application shows the claims as filed; the granted patent shows the claims as allowed, which are often narrower. Check which document you are reading.

Cited, checkable answers

Each answer carries inline citations to the supporting excerpt, with a page, column or section reference when the patent provides one, and Search+ does not invent locations.

Older patents as scans

Many older patents are published only as page images. Search+ reads those with OCR; chemical formulas, claim numbering and figure labels are where recognition errors show up, so check them in the cited excerpt.

What is a patent?

A patent is a public document granted by a patent office that gives its owner exclusive rights in an invention for a limited time, in exchange for disclosing how the invention works. It consists mainly of a description of the invention and a set of claims that define the protected scope.

A published patent application is not a granted patent: it shows what the applicant asked for, which may change or be refused. Search+ reads either and answers from the text; it does not assess validity, infringement or freedom to operate.

Patent questions

Can Search+ explain what a patent's claims cover?

It can break a claim into its elements and point to where the description explains each one, with citations. Interpreting claim scope legally is work for a patent professional.

Can it find where a claim term is defined in the description?

Ask whether and where the patent defines the term. The answer cites the passage, so you can read the definition in context.

Can it compare a patent application with the granted patent?

Put both publications in one workspace and ask how the independent claims differ. The answer cites each document's claim language.

Is this legal advice about infringement or validity?

No. Search+ helps you read and find text in patents. It does not give legal advice; questions of infringement, validity or freedom to operate need a qualified patent attorney or agent.

Will it read an older patent saved as page images?

Yes. Image-only patent documents are read with OCR, so older patents work too. Read the cited claim text against the original image before you rely on its exact wording, since one changed word can change claim scope.

Could an answer misread a claim?

Yes. Claim language is precise and AI answers can be incomplete or wrong, so always read the cited claim text itself.
