Patent, Trademark and IP Litigation Attorneys
Sherinian Law prepares patent applications and guides them through the USPTO for inventors and technology companies, with inventions ranging from software and networked systems to electronic devices. We also handle trademark registrations, oppositions and cancellations, and represent clients in patent and trademark disputes. Two of our partners, one trained in electrical engineering and one in computer science, also litigate intellectual property cases. We work with clients across the Chicago area and throughout the United States.
Why our engineering and litigation backgrounds matter to your patent
Konrad Sherinian studied electrical engineering and applied physics at Case Western Reserve University and has written more than 200 patent applications. Edward Bi holds a master's degree in computer science. He worked as an engineer and engineering manager on computer, software and wireless communication products, and he started two technology companies before he became a patent attorney.
That background helps from the first conversation. When you explain how your system works, we can follow the technical details and ask the questions that help us describe it accurately. A patent application has to describe the invention clearly enough for others in the field to understand it, and its claims set the boundaries of what the patent covers. Getting both right starts with understanding how the invention actually works.
Litigation adds a second perspective. Konrad represents clients in intellectual property cases in federal court and has served as lead counsel before the Patent Trial and Appeal Board and the Trademark Trial and Appeal Board. Edward began his legal career as a technical expert, analyzing infringement and invalidity in patent lawsuits. That experience shows how claims are read in a dispute and how they can be challenged with prior art, meaning earlier patents, publications and products. We bring that perspective to the applications we prepare, so the possibility of a future challenge is considered from the start.
Recent patents issued with our firm as counsel
Patent records are public. Each patent below lists The Law Offices of Konrad Sherinian, LLC as the attorney or firm of record, and each links to its published record.
Real-time data transmission
Checks whether a network can handle a live data transfer before it begins, based on predictions of how that network is likely to perform. If the connection looks too weak, the system suggests waiting, connecting through a different access point or switching networks.
Layered encryption for stored secrets
Passwords and other sensitive data stored on a device are protected by several layers of encryption. The keys are tied to the device's hardware and the user's account and password, and the system also uses a Secure Element (a dedicated security chip) and a sandbox that keeps the data isolated from other software.
A device with no external switch
The electronics are sealed inside, with no power button. Spinning the device turns it on, and it can be turned off from its touchscreen or automatically. The inventor is based in Aurora, Illinois, and attorney Jeffrey S. Dixon is named on the patent with the firm.
These are a small sample. You can see more of our work on software and computer-implemented inventions on our software patent page.

Patents
We prepare and file patent applications for software and computer-implemented inventions, including SaaS platforms, mobile apps, data systems and software-controlled devices.
We also file utility patent applications for machines, electronics, consumer products and medical devices, and design patent applications that protect how a product looks. A provisional application can secure an early filing date while an invention is still being refined, provided it describes the invention fully enough and a nonprovisional application follows within 12 months.
After filing, we carry the application through examination, responding to office actions when the examiner rejects claims, including objections that a software invention is not eligible for a patent. If another firm filed your application, we can take it over and continue the prosecution.
Trademarks
We file and prosecute trademark registrations with the USPTO. The Trademark Trial and Appeal Board (TTAB), within the USPTO, hears disputes over trademark registration, including oppositions and cancellations. Trademark infringement claims are separate and are litigated in court.
We handle TTAB oppositions, which challenge an application before it registers, and cancellation proceedings, which seek to remove a registration that has already issued, whether you are bringing the challenge or responding to it. These are contested proceedings with discovery, evidence and briefing, decided by the board rather than by a court.
Litigation
When rights are already in dispute, we represent clients in federal court in patent infringement and validity disputes and in trademark litigation, including motions for preliminary injunctions.
Some patent disputes also involve inter partes review (IPR), a proceeding before the USPTO's Patent Trial and Appeal Board that challenges issued patent claims based on earlier patents or publications. We have used IPR as part of a client's defense.
Representative IP Disputes
Patent defense for a home-improvement retailer
A welding-helmet manufacturer sued a major U.S. home-improvement retailer for patent infringement. We commissioned a prior-art search, which found that the helmet the manufacturer said embodied its patent had been shown at a trade show more than a year before the patent application was filed. The case settled quickly, on favorable terms for our client.
Inter partes review for an aftermarket lighting supplier
A major supplier of aftermarket automotive lights faced a patent claim from a competitor. Our review of the prior art found that the competitor's product was based on a foreign design. We prepared and filed a petition for inter partes review, and the matter soon settled on terms that benefited our client.
Trademark defense for a novelty-gifts supplier
A competitor sued a major novelty-gifts supplier, claiming exclusive rights to well-known words used in advertising and products, and sought a preliminary injunction to stop our client from selling during the holiday season. The injunction was defeated, and our client continues to operate. The case is still pending.
