Patent Services for Patent Pending Applications
Pre-grant professional services start at our minimum fee of $640. Veterans and women receive a 25% discount on professional fees, reducing the minimum to $480. The fee for your matter depends on the application record, response required, and scope of representation. Applicable official fees and outside costs are separate. Contact us for a current written estimate.
Our engagement terms identify which preparation, filing, and prosecution services are included and which require separate authorization. Review our patent service fees, prior art search and patentability study costs, and cost calculator with the scope of your matter in mind.
Your Invention is Patent Pending, Now What?
Pre-grant services address a pending application before issuance or abandonment. A final rejection does not necessarily end prosecution, but further action must be timely and procedurally available. Depending on the case, options may include an after-final response, appeal, an RCE where permitted, or an appropriate continuing application. None is an automatic extension of every application.
Office actions are a normal part of examination, including for carefully prepared applications. A filing receipt, publication notice, and notice of allowance are not the only communications a well-prepared application may receive. Services during examination may include:
- Responding to office actions from the examiner
- Writing and filing patent application amendments
- Writing and filing new claims
- Conducting examiner interviews
- Petitions and patent application actions
Ownership changes and other developments may require additional filings. The appropriate action depends on the application and the event; a general opposition procedure should not be assumed. Read more about what happens after filing a patent application.

Responding to Office Actions from the Examiner
Responding to an office action is submitting a responsive written reply back to the Patent Office. The USPTO sends communications to the applicant as action on the patent application happens. In particular, when the examiner examines the application, they will send communications called office actions that the applicant will need to respond to in order to continue seeking patent protection. USPTO office action responses must include a complete response to all issues raised in the office action.
Office actions include both rejections and objections. The responses to office actions are written to provide a proper and complete response to all rejections and objections raised by the examiner. Carson Patents highly recommends patent practitioner help to respond to USPTO office actions. Contact us for help responding to an office action in your patent application.
Writing and Filing Patent Application Amendments
An office-action response may include amendments to the claims, specification, or drawings where appropriate. Amendments must comply with USPTO rules and may not introduce new matter into the application. A later development that lacks support in the original disclosure may require a separate filing strategy. Contact Carson Patents for help evaluating and preparing a response.
Writing and Filing New Patent Claims
Pre-grant patent services include revising the existing claims in an application. For pending patents, and in response to office actions, revising existing claims and writing new claims may become necessary. Generally, submitting new claims and revising and resubmitting existing claims occurs as part of office action responses. Above all, claims must be in proper form, not indefinite, and supported by the written description and the drawings. Carson Patents provides writing new and revised patent claims. Contact us to get new or revised claims written for your pending patent application.
Conducting Examiner Interviews
Patent examiner interviews are audio or video interviews with the examiner about the details of a patent application. Examiner interviews are conducted for many reasons. For example, we can discuss examination details and the reasoning for claims rejections and objections. Further, we can propose new or amended claims.
There are at least three examples of good reasons to conduct an examiner interview: sharing understanding of the invention, discussing the patentability of the claims, and to determine election options after a restriction office action. Examiner interviews can help determine the best way to respond to an office action. Frequently, examiner interviews can be pivotal during the prosecution of a patent application. Therefore, Carson Patents highly recommends patent practitioner help for examiner interviews.

Pre-Grant Patent Services Examples with Costs
Question: What is pre-grant patent?
Answer: A patent pending application.

Utility Patent Application Office Action Response Example A
We wrote and filed a patent application for a new electric appliance. The USPTO patent examiner found: 1) a spelling error; 2) an inconsistent element reference between the figures and the written description; 3) objections to the dependent claims for lack of proper antecedent basis; and 4) rejection of the independent claims as obvious to a person skilled in the art. Carson Patents amended the claims, figures, and specification to correct for 1, 2, and 3 at no cost, because we view these corrections as administrative errors. Correcting for 4, the claims rejection, required writing 17 new claims and amending the written description. The reported fee for that historical matter was $1,060. This is not a current quote; any amendments had to remain within the original disclosure.

Utility Patent Application Office Action Response Example B
An inventor previously used an inventor assistance “service” who had written and filed a patent application for a new electric appliance. The USPTO patent examiner found: 1) numerous spelling and grammar errors; 2) improper drawings; 3) the abstract was written in improper language; 4) objections to all claims for lack of proper antecedent basis and lack of support in the written description; and 5) rejections of all claims as obvious to a person skilled in the art. Carson Patents conducted an examiner interview to discuss the objections and rejections for $840. The reported fee for amending the claims, abstract, figures, and specification was $2,480. These are historical matter amounts, not current prices. Amendments cannot add missing subject matter to the original application.
