Patent Prosecution Services in Las Vegas

Filing a patent application begins the examination process. It does not end it.

The United States Patent and Trademark Office assigns a patent examiner to review the application. The examiner may allow the claims, object to parts of the application, or reject some or all of the claims.

The Thornton Firm represents independent inventors, entrepreneurs, startups, and businesses during patent prosecution. We work with clients in Las Vegas, throughout Nevada, and across the United States.

What Is Patent Prosecution?

Patent prosecution is the process of seeking a patent before the USPTO.

It includes communicating with the patent examiner, reviewing Office Actions, preparing legal arguments, amending claims, conducting examiner interviews, and addressing procedural requirements.

Patent prosecution is different from patent litigation. Prosecution takes place before the USPTO. Litigation generally involves disputes in federal court.

The goal of patent prosecution is to obtain meaningful patent protection while responding to the legal and technical issues raised by the examiner.

What Is an Office Action?

An Office Action is a written communication from a patent examiner.

The Office Action may explain why the examiner believes that one or more claims should not be allowed. It may also identify objections, informalities, or procedural requirements.

An Office Action does not necessarily mean that the application has failed. Rejections are common during patent examination.

The applicant usually has an opportunity to respond. The response may include legal arguments, claim amendments, technical explanations, supporting evidence, or a combination of these approaches.

Common Patent Rejections

Patent examiners may reject claims for several reasons.

A rejection under Section 101 may assert that the claims do not recite patent-eligible subject matter. These rejections often arise in applications involving software, business methods, data processing, diagnostic methods, or other computer-implemented inventions.

A rejection under Section 102 may assert that one prior-art reference discloses every element of a claim.

A rejection under Section 103 may assert that the claimed invention would have been obvious. The examiner may rely on one reference or combine several references.

A rejection under Section 112 may concern claim clarity, written-description support, enablement, or the form of the claims.

An Office Action may raise several types of rejection at the same time. Each issue requires a separate analysis and response.

Responding to an Office Action

An effective response begins with a careful review of the application, the claims, the examiner’s reasoning, and the cited prior art.

The first question is whether the rejection is legally and technically correct. A reference may fail to disclose a required claim element. The examiner may also rely on an unsupported combination of references or interpret the claim language too broadly.

In some cases, legal argument may be sufficient. In others, amending the claims may provide a clearer path toward allowance.

A claim amendment should do more than obtain short-term approval. It should preserve commercially meaningful protection whenever possible.

The original application limits the amendments available later. This is one reason careful patent drafting matters from the beginning.

Examiner Interviews

An examiner interview allows the patent attorney and examiner to discuss the application directly.

The interview may clarify the examiner’s position, identify disputed claim language, or explore a possible amendment. It can also reveal whether the examiner finds a particular argument persuasive.

An interview does not replace the written response. Important arguments and amendments must still be placed in the official record.

A productive interview can make the written response more focused. It may also reduce unnecessary rounds of prosecution.

Claim Amendments

Claims may be amended to clarify the invention or distinguish it from the prior art.

An amendment may add a structural relationship, functional limitation, process step, control requirement, or other feature supported by the original application.

Every amendment involves a tradeoff. Adding a limitation may improve the chances of allowance, but it may also narrow the scope of protection.

The objective is not simply to obtain any patent. The objective is to pursue claims that provide practical value.

We work with clients to understand which features matter commercially before making significant claim amendments.

Non-Final and Final Office Actions

A first substantive rejection is often issued as a non-final Office Action. The applicant generally has the right to respond with arguments and amendments.

The examiner may then allow the claims or issue another Office Action. A later rejection may be designated as final.

A final Office Action does not always end the application. The available options may include an after-final response, an examiner interview, a Request for Continued Examination, an appeal, or another form of continued prosecution.

The correct approach depends on the rejection, the prosecution history, the available disclosure, and the client’s objectives.

Requests for Continued Examination

A Request for Continued Examination allows the applicant to reopen prosecution after a final rejection.

An RCE may be appropriate when additional claim amendments, evidence, or arguments could advance the application. It gives the examiner another opportunity to consider the application.

An RCE also requires an additional USPTO fee. It may add time and expense to the process.

Filing an RCE should therefore be a strategic decision. It should not become an automatic response to every final rejection.

Patent Appeals

An applicant may appeal a rejection to the Patent Trial and Appeal Board.

An appeal may be appropriate when the examiner maintains a rejection that the applicant believes is legally or factually incorrect. The appeal process focuses on whether the examiner properly rejected the claims.

Appeals require careful briefing and a strong understanding of the prosecution record. They may also take significant time.

In some cases, continued examination offers a better path. In others, an appeal may be necessary to obtain meaningful review of the examiner’s position.

Restriction Requirements and Divisional Applications

The USPTO may determine that an application contains more than one distinct invention. The examiner may then issue a restriction requirement.

The applicant must elect a group of claims for examination. The remaining claims may be pursued in one or more divisional applications.

Restriction practice can affect cost, timing, and claim strategy. It may also create opportunities to pursue different aspects of the disclosed invention in separate applications.

We help clients evaluate the available claim groups and preserve important subject matter when practical.

Continuation Applications

A continuation application may allow an inventor to pursue additional claims based on an earlier disclosure.

A continuation can focus on a different aspect of the invention, seek claims of a different scope, or preserve pending rights while another application moves toward issuance.

Continuation practice can be valuable when an invention has several commercially important features. It can also help an inventor respond to changes in a market or competing product.

Any continuation strategy must account for deadlines, cost, and the disclosure contained in the original application.

Information Disclosure Statements

Patent applicants and others involved in prosecution have a duty to disclose information material to patentability.

An Information Disclosure Statement allows an applicant to submit patents, published applications, articles, and other references for the examiner’s consideration.

Submitting a reference does not admit that the reference prevents patentability. It places the information before the examiner and makes it part of the record.

Timing matters. Additional fees or procedural requirements may apply when an IDS is filed later in prosecution.

Taking Over an Existing Patent Application

An inventor may need new counsel after an application has already been filed.

We can review an existing application, its claims, the prosecution history, and any pending Office Action. We can then evaluate the available response options and identify upcoming deadlines.

Changing attorneys does not extend a USPTO deadline. A new attorney needs enough time to study the record and prepare a complete response.

Inventors considering a change in counsel should act promptly.

Working Directly with a Patent Attorney

Patent prosecution requires an understanding of both the invention and the law.

We explain the examiner’s position in practical terms. We also discuss the available options, likely costs, and potential effects on claim scope.

The client remains involved in important prosecution decisions. This is especially important when an amendment may affect a commercially valuable feature.

The Thornton Firm handles patent-prosecution matters on a flat-fee basis whenever practical. We discuss the scope of the work and anticipated fees before beginning a response.

Meetings may take place by Zoom, telephone, or in person when appropriate. We represent inventors throughout Las Vegas and Southern Nevada. We also represent applicants across the United States.

Speak with a Las Vegas Patent Attorney

An Office Action should be taken seriously, but a rejection does not necessarily mean that an invention cannot be patented.
