How to Choose a Patent Attorney
Choosing a patent attorney is one of the most consequential decisions for any inventor or technology company.
The attorney you select shapes the strength of your patent claims, the speed of prosecution, and your ability to enforce or license your patents years later. A weak patent application can be expensive to fix and sometimes impossible to repair.
For most companies, this decision is not just about getting a patent. It is about whether the resulting patent will support funding, licensing, or enforcement over the long term.
This guide walks through what actually matters when evaluating patent counsel, what good answers to your diligence questions sound like, and the red flags that should make you keep looking.
What a patent attorney actually does
A patent attorney is a licensed lawyer who has also passed the USPTO patent bar exam (which is separate from the state-level “bar exam” that most people have heard of), qualifying them to practice before the United States Patent and Trademark Office.
Patent attorneys must hold a technical or scientific degree in addition to their law degree, because patent prosecution requires understanding the technology being patented.
A patent agent is a person with a technical or scientific degree who has passed the USPTO patent bar exam, but who has not gone to law school and is not an attorney admitted to practice in any state.
Patent attorneys and patent agents typically focus on one of two practice areas:
- Patent prosecution: drafting and filing patent applications, responding to USPTO examiner rejections, and shepherding applications through to issuance. This can be done by both patent attorneys and patent agents.
- Patent litigation: defending or asserting patents in federal court, before the Patent Trial and Appeal Board, or at the International Trade Commission. These can generally only be handled by patent attorneys (not patent agents).
Some firms handle both. Others specialize. The attorney you need depends on whether you are building a portfolio, defending against a challenge to your patent or an assertion of infringement against your products, or asserting your patents against an infringer.
For most inventors and growing technology companies, the immediate need is patent prosecution. That work establishes the foundation everything else depends on.
Our attorneys hold engineering and science degrees and focus on patent prosecution and intellectual property strategy for technology-driven companies.
The technical background question matters more than people realize
Patent claims are unique blend of technical writing and legal writing.
A patent attorney drafting claims for machine-learning systems needs to understand modern model architectures, training methodologies, and how examiners evaluate software-related applications under Section 101 patent eligibility standards, where claims are often rejected as abstract ideas.
A patent attorney or patent agent drafting claims for wireless communications needs to understand signal processing, protocol layers, and how to navigate examination in technology areas with dense prior art.
A patent attorney or patent agent with a chemistry background will not write strong software patent claims, no matter how skilled they are. A software-trained attorney or agent will not draft strong claims for a novel synthesis route.
When evaluating candidates, ask about the technical fields where they have actively prosecuted patents, not just degrees they hold.
There is a meaningful difference between an attorney who happens to hold a technical degree and one who has spent years prosecuting patents in that specific technology area.
A good answer sounds like:
“I have a background in electrical engineering, and I’ve prosecuted patents in areas like wireless communications, semiconductor design, and software systems. For pharmaceutical chemistry or biologics work, I would refer you to someone with that specific background.”
A weak answer sounds like:
“We handle all areas of patent law. Our firm has experts in every technology.”
Be skeptical when no one is willing to acknowledge a limitation.
What to ask about prosecution experience
USPTO registration is the minimum qualification. It tells you the attorney can file before the Patent Office. It does not tell you whether they file well.
Better diligence questions include:
- How many patent applications do you typically handle each year? An attorney should be actively drafting and prosecuting applications, not only working on litigation or management.
- What technology areas do you most often work in? Different examination groups have different practices, prior art, and rejection patterns.
- What is your typical approach to a Section 101 rejection? A capable attorney can describe specific strategies such as framing technical improvements, emphasizing implementation details, and restructuring claims.
- Can you describe a recent application where you overcame a rejection? The answer should include the examiner’s concerns, the arguments made, and how the issue was resolved.
A good patent attorney or agent will answer these questions specifically. A weak attorney will speak in generalities.
How to evaluate strategic thinking
Patent prosecution is not just about getting patents granted. It is about getting patents granted that actually protect your business.
The strongest patent attorneys and patent agents think about:
Claim scope versus enforceability — broader claims are valuable but more vulnerable to challenge
Continuation strategy — keeping options open as products evolve
Prosecution history estoppel — statements made to examiners can permanently limit enforcement
International strategy — how U.S. filings affect foreign protection under the Patent Cooperation Treaty (PCT) and related systems
For example, we have seen situations where an application appeared strong at filing but was narrowed significantly during prosecution because of early statements made to the examiner. Those statements later limited how the patent could be enforced.
When interviewing candidates, describe your business and ask how they would approach building a portfolio. The answer should connect patent strategy to your commercial goals.
Cost and billing transparency
Patent work involves three cost components:
- Attorney fees
- USPTO filing and maintenance fees
- Drawings, documentation, and related expenses
A non-provisional patent application often costs in the range of several thousand to tens of thousands of dollars in attorney fees, depending on the complexity of the technology. Office Action responses typically involve additional costs, and most applications go through multiple rounds of examination.
Be wary of attorneys offering unusually low flat rates. Patent applications that look inexpensive upfront often cost more later, either because they require significant revision or because the resulting patent is too narrow to be useful.
Ask for written estimates that break out fees clearly. Ask what is included, what is not, and how additional work is billed.
Even though it is difficult to provide exact costs top-to-bottom, a good firm will be straightforward about estimated cost ranges and the factors that affect them.
Red flags during the evaluation process
Some warning signs are obvious. Others are more subtle.
Unwillingness to discuss specifics about past work
Attorneys cannot disclose confidential client details, but they should be able to describe the types of issues they have handled and how they approached them.
Promises about outcomes
No attorney can guarantee a patent will issue. Anyone suggesting otherwise is not being realistic about the process.
Reluctance to identify limitations
Strong attorneys are clear about what they do well and where they would refer work.
Slow or inconsistent communication
Initial responsiveness is often a good indicator of how the relationship will function under deadlines.
Vague answers about who will do the work
At larger firms, the attorney you meet may not be the one drafting your application. This should be clearly explained.
Pressure to file before you are ready
Filing too early can result in incomplete disclosure that limits future claim scope.
What to expect during a first conversation
A productive initial discussion typically includes:
- A high-level description of your invention
- Your business goals and timeline
- Whether a patent is the right form of protection
- Realistic expectations for timing and cost
- The attorney’s relevant experience
You should not expect a detailed patentability opinion during an initial call or meeting. That requires dedicated analysis. You should expect a clear discussion of next steps.
Working effectively with patent counsel
Choosing the right attorney is only the first step. The quality of the working relationship matters just as much.
Strong engagements typically involve:
- Direct communication between attorney and inventors
- Early involvement in product and strategy decisions
- Clear explanation of tradeoffs in prosecution decisions
- Regular review of the patent portfolio as the business evolves
Patent work is collaborative. The best results come from attorneys and agents who understand both the technology and the business context.
When to switch counsel
Sometimes the relationship is not working. Common reasons companies change patent counsel include:
- Unresponsive communication that creates risk around USPTO deadlines
- Errors that affect claim scope or weaken patent protection
- Lack of strategic guidance beyond filing individual applications
- Cost unpredictability without clear explanation or planning
- Changes in firm staffing that reduce technical expertise
Switching counsel is not unusual, especially as companies grow and their needs become more complex.
