Intellectual Property Disputes

Intellectual Property Litigation

Two major categories of intellectual property are U.S. patents and U.S. trademarks. The United States Patent and Trademark Office (USPTO) is the Federal agency that grants U.S. patents and registers U.S. trademarks.

A U.S. patent is:

“an intellectual property right granted by the government of the United States of America to an inventor ‘to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States’ for a limited time in exchange for public disclosure of the invention when the patent is granted.”

A U.S. trademark or service mark is:

“a word, name, symbol, device, or any combination thereof, used to identify and distinguish the goods and services of one seller or provider from those of others and to indicate the source of the goods and services. Although Federal registration of a mark is not mandatory, it has several advantages, including notice to the public of the registrant’s claim of ownership of the mark, legal presumption of ownership nationwide, and a presumption of the exclusive right to use the mark on or in connection with the goods or services listed in the registration.”

During the 20-year period ended December 31, 2017, the USPTO granted 4.5 million patents, of which approximately 90 percent were utility, 9 percent were design, and less than one percent were plant. In each of the three classifications of U.S. patents, more than twice as many patents were granted in 2017 as in 1998. Both U. S. patents and trademarks are ubiquitous. The USPTO issued certificates of registration for approximately 3.2 million trademarks and renewed approximately 830,000 trademarks during the 20-year period ended December 31, 2017.

Given the proliferation of U.S. patents and trademarks, it is not surprising that, in recent years, complaints filed in the U.S. District Courts alleging infringement of one or more U.S. patents or trademarks annually number in the thousands.

Patent Infringement

The proliferation of U.S. patents is fueled by the rapid pace of global technological innovation. Today, major public companies may own U.S. patent portfolios that number in the tens of thousands. Innovations have led to the creation of products that are increasingly technologically complex. Given the complexity of some products and their myriad of features and functions, it is understandable that they may contain hundreds of components and may utilize the patented inventions of multiple patents, even hundreds or thousands of patents. The technological complexity of products combined with the intricacies of the law and precedents set by the courts regarding damages in patent infringement matters, together with the typical high volume of documents produced in patent matters tends to create thousands of pieces of evidence that may resemble a jigsaw puzzle.

Trade Infringement Litigation

Per the USPTO,

“trademark infringement is the unauthorized use of a trademark or service mark on or in connection with goods and/or services in a manner that is likely to cause confusion, deception, or mistake about the source of the goods and/or services”.

If a trademark owner has reason to believe that its mark is being infringed, it may file a civil action in either Federal court or state court depending on the facts and circumstances of the matter. Typically, trademark owners sue for infringement in Federal court according to the USPTO. In these matters, the court may find that the trademark owner is able to prove infringement or, on the contrary, that the defendant has not infringed the trademark or that the trademark owner may not prevail in the matter for other reasons. If the trademark owner proves infringement, the Court may provide remedies in the form of various orders and/or injunctions and may award monetary damages to the trademark owner. Monetary damages may be awarded by the court subject to the principles of equity, such as the profits earned by the defendant as a result of its trademark infringement; the damages incurred by the plaintiff as a result of the defendant’s infringement; the plaintiff’s costs associated with the action; the plaintiff’s attorney fees associated with the action; prejudgment interest; statutory damages; and other issues pertaining to willfulness. The types of recoverable damages are described in the Lanham Act for Federal matters and in various state statutes for matters filed in one of the state courts.

BTZ professionals may assist the court in determining damages in trademark matters by providing various financial opinions on behalf of the trademark owner (the plaintiff) or the alleged trademark infringer (the defendant). These financial opinions may pertain to the profits earned by the defendant associated with its trademark infringement, the damages incurred by the plaintiff as a result of the defendant’s infringement, and other relevant financial matters.
