A patent practice supported by more than 20 years of intellectual property work for inventors in Chicago and the surrounding region.

A sale or public disclosure made before filing can place patent protection out of reach. The Patent Baron PLLC prepares and prosecutes patent applications on behalf of inventors and growing companies. Working with a Chicago, IL patent lawyer at our firm places over two decades of intellectual property experience and an engineering background behind your filing. The strength of a patent rests on the application, and that work warrants careful attention from the start. Reach out to schedule a consultation about your invention.

Patent Lawyer Chicago, IL

A patent is a legal right, issued by the federal government, that lets an inventor prevent others from making, using, or selling what they have created for a set number of years. In return, the inventor places a full explanation of how the invention works on the public record.

A patent works differently from a trademark or a copyright, and each protects something distinct. Trademarks cover the identifiers of a brand, from its name to its logo. Copyrights cover creative works. A patent protects the function of an invention, how it operates and how it is built. Patents are issued by the United States Patent and Trademark Office, a federal agency, and the protection a patent secures applies nationwide. That national scope is why The Patent Baron PLLC can represent inventors in Chicago and well beyond Illinois.

Types of Patent Cases We Handle in Chicago

No two inventions follow the same path to protection. Some clients bring us a working prototype. Others bring a concept and a looming disclosure date. Wherever an inventor stands in that process, we can help. The services described below are the ones Chicago clients turn to us for most.

• Utility patents. Most inventions are protected by a utility patent, which covers how something works, what it does, and how it is used. We prepare the written description and the claims, then represent the application through the examination process. Clients come to us with machines, processes, devices, and improvements on the different types of patentable technology. The drafting stage is where much of a patent’s lasting protection is either secured or lost.
• Design patents. When a product’s value lies in how it looks rather than how it works, a design patent is the appropriate route. We handle applications directed at the ornamental appearance of an article. These filings often move faster than a utility application, an advantage that can matter when a product cycle is short.
• Provisional patents. A provisional application locks in an early filing date and gives an inventor a year to refine the concept before filing a full application. We help clients judge whether that step fits their situation and prepare it properly. The value of a provisional rests entirely on the detail inside it. A sparse one offers little real protection.
• Patent searches. Investing in an application makes more sense once an inventor knows what already exists. We conduct prior art searches, which review earlier patents and publications to indicate whether an invention is patentable and what previous work it will need to be distinguished from. Inventors who skip this step sometimes pay for it later, after time and money have already been committed.
• Patent filings. Assembling and submitting the complete application is detailed work, spanning the written description, the claims, and the formal drawings. We manage the full process for filing a patent, keeping the application in line with the patent office’s requirements and giving the invention a strong start.
• Rejection appeals. A rejection from an examiner is a routine part of the process and seldom final. We respond to office actions and, when the situation justifies it, pursue appeals to contest a rejection and keep an application advancing toward a grant. Many applications that appear stalled can still reach a grant.

Engineering Training Behind Every Filing

J. Baron Lesperance trained as an engineer before he ever practiced law. He holds a Bachelor of Science in Mechanical Engineering and a Master of Science in Electrical and Computer Engineering, along with a Master of Laws in Intellectual Property. A patent application can only protect an invention it accurately describes, and accurately describing it requires a lawyer who understands the technology itself, not just the law surrounding it.

For a Chicago inventor, that means an application prepared by someone equipped to handle both the technical details and the legal side of the work.

What Is Important To Understand About Patent Cases?

Patent Types, Requirements, and the Path to a Grant

A patent is never automatic. Before one is granted, the invention has to clear several requirements, and falling short on any of them usually prevents the application from going further. These are the points an examiner weighs.

• Novelty. The invention has to be new. If it has already appeared in earlier products or publications, it will not qualify.
• Non-obviousness. Being new is not enough. The invention also has to be more than an obvious improvement that a skilled professional in the field would view as an expected change.
• Usefulness. The invention has to genuinely work and serve a real, practical purpose.
• What can be patented. Not every creation is eligible. The invention has to fall within the categories the law recognizes.
• Full disclosure. The application has to describe the invention clearly enough that someone else could build it and use it.

What Are Important Aspects of a Patent Case?

A patent matter usually turns on timing and drafting. An invention shown to the public before filing can lose its protection altogether, and claims that are written loosely can leave even a granted patent easy to work around.

• Filing before any public sale or disclosure preserves your ability to obtain a patent.
• Careful research into earlier inventions produces claims that can withstand examination.
• Carefully written claims define exactly how far your protection reaches.
• Thorough records of the invention’s development help the application stand up to scrutiny.

What Is The Patent Case Timeline?

Getting a patent takes time, and most of that timing is out of your hands. The stages below give a general sense of what the wait involves.

• A search for similar inventions and the drafting of the application come first. Plan on a few weeks for both.
• From there, the filed application waits its turn, often for many months, before an examiner gives it a first review.
• The examiner will usually come back with a formal letter of questions, and each one sets a deadline for your reply.
• Answering those questions, and settling the exact scope of the patent, is normally the longest phase of all.
• How long it takes to get a patent approved varies, but a grant commonly follows a few years after the original filing date.

What Should You Bring to Your Patent Consultation?

Good preparation turns a first meeting into a productive one. A few things are worth pulling together beforehand:

• A description of the invention, written plainly, and the problem it was made to solve.
• Visual material of any kind, from rough sketches to a working prototype.
• Notes on when you first developed or disclosed the idea.
• Any products already on the market that do something similar.
• The name of each person who had a hand in creating it.

We use that first meeting to study the invention and talk through whether protection is worth pursuing. By the end, most inventors understand whether a patent is within reach and what pursuing one would take.

What Are Important Legal Resources for Patent Cases?

There is no state-level patent system in the United States. Patents are granted under federal law alone, which is why the sources below all point to national agencies that inventors can consult directly.

• A patent basics page is the best place for a first-time inventor to start, covering core concepts in plain terms.
• The USPTO’s patent search tools let you look through granted patents and published applications before you file.
• The USPTO fees page outlines the costs for the various stages of an application.
• The USPTO inventors and entrepreneurs resources section is built for independent inventors and small businesses.
• The U.S. Small Business Administration gives broader guidance for inventors who are also launching a business.
