Avoiding Patent, Trademark, and Copyright Problems


Patents, copyrights and trademarks, as well as know- how or trade secrets, are often collectively referred to as intellectual property. Many firms have such property without even being aware of it or of the need to take measures to protect it.

Many people's notions of intellectual property are unrealistic. Some believe, for example, that having a patent on a product will enable one to succeed in the marketplace. Consequently, they may spend thousands of dollars to obtain the exclusive rights to market something that no one wants or can afford to buy. Others may conclude that intellectual property protection is not worth the expense and bother.

People who may not be interested in protecting their own rights still must take precautions to avoid infringing on the rights of others. This calls for more than the avoidance of copying. Copying is unavoidable; it is a way of life and one way in which we learn. But, one can easily infringe on the rights of others without deliberately imitating specific features of goods or services.

This publication addresses the steps newcomers to a market should take to avoid infringement and when they should take them.


Most people have heard variations on a remark attributed to Ralph Waldo Emerson: If a man can make a better mousetrap than his neighbor, though he builds his house in the woods the world will beat a path to his door. To keep the discussion concrete, let's imagine a present day inventor of a new mousetrap who not only invents a better mousetrap but is also successful in marketing it. The higher the inventor's profit margin, the more others will want to copy his invention. Let's assume that the inventor selects Figaro as the brand name and actively promotes the product. However, he does not legally protect his invention, but relies on the consumers' loyalty, goodwill and brand identification to ensure future sales.

Taking measures to develop loyalty and goodwill may be sufficient until a larger and better known competitor turns up. For example, what if economies of scale and lack of development costs mean that the competitor can sell the same mousetrap for 20 percent less? Goodwill may not be enough to ensure customer loyalty at a higher price. A patent would be much more helpful, because it would prevent the competitor from selling the new trap until well after the original firm had a chance to get on its feet. This situation illustrates that it is the smaller firm that often has the most to gain from protecting intellectual property.

As bad as the situation is without patent protection, it could be worse. Let's assume that customers are so taken by the Figaro promotion that they are willing to pay the 25 percent premium the firm charges in order to stay in business. Imagine what would happen if the company had to stop using that name or had to face an expensive lawsuit. Imagine what would happen if it turns out that someone else actually has a current patent on one or more features of the better mousetrap. By failing to consider the intellectual property of others, the new firm would not only be forced to stop selling under the name Figaro, but might be forced to stop selling the mousetrap altogether.


Utility patents - what people usually mean when they use the term patents - provide 17 years of exclusive rights for inventions that deal with the way things work. Design patents afford 14 years of protection for significant improvement in the appearance of useful items, such as car bodies or furniture. Both of these patents do more than prevent copying; they forbid the making, using or selling of an invention similar to or the same as the protected invention, even though the second invention was independently created. (Plant patents, which will not be covered in this discussion, may not give the same protection.)

Copying may actually be a way to avoid infringement. The inventor of the mousetrap might have avoided potential problems by using technology that was described in a printed publication, publicly used or on sale. Products that are on sale and give no notice of patent coverage are relatively free from the risk of infringement.

Any person trying to market fairly new technology that doesn't appear to be patented should keep in mind that an inventor has one year from public sale or disclosure within which to file a patent application. In addition, because patents often take two or more years to obtain, there is still a chance that a patent could be issued at a later time. Although there is no liability for infringement prior to issuance of a patent, a competitor would have to cease making, using or selling the technology once the patent was issued, thus risking the loss of both start-up costs and inventory.

Of course, if our inventor was determined to make a better mousetrap, there would be no interest in copying something else in the market. Still, before spending too much time and money on research, the inventor should ensure that others do not have exclusive rights in the area being explored. The inventor certainly should not assume that, because a product is not on the market, it is unpatented. As many independent inventors have learned to their chagrin, it is usually easier to patent something than to market it profitably.


The inventor should hire a patent attorney or agent to conduct an infringement search. A patent agent is a technically trained person who has passed a special examination given by the U.S. Patent and Trademark Office; a patent lawyer is one permitted to draft contracts and provide other general legal services. Patent searches can be expensive if one must consult foreign records; it is much less costly to determine whether technology is currently patented in the United States. Yet, as we will see, there is value in going somewhat beyond that point.

A search might reveal that (1) someone else had a patent that has since expired, i.e., the information patented is now in the public domain; (2) no current or expired patents cover the area of proposed research or (3) someone else has a current patent covering all or part of the proposed design. Let's consider these potential results in order.


If the mousetrap (or an obvious variation) was disclosed in an expired patent, the inventor is free to manufacture and market it without concern for the patent laws. Also, even if the inventor didn't find exactly what he or she originally had in mind, a host of good and freely used ideas that are even better might have been discovered. These alone could be worth several times the price of the search in saving research and development time.


If, after a thorough search, our inventor's proposed improvements to the mousetrap seem not only to be novel but also to offer significant advantages over the prior design, the inventor may seek a patent and/or begin selling the mousetrap without further ado. If, however, the inventor begins selling without first filing a patent application, he immediately forfeits possible protection in many other countries and also forfeits any possibility of patent rights in the United States after one year.


If an unexpired patent is found to cover any part of the proposed mousetrap design, the inventor knows that he is not free to use it without a license. Infringing on a current patent exposes one to a suit for damages as well as an injunction against future use. Even an injunction might mean substantial costs, including the loss of current inventory, and a patent covering even a small feature of the new mousetrap might give rise to the need to retool. Although deliberate infringement is more serious, ignorance of others' patents is no defense.


Trademarks (or brand names) indicate commercial source. Trademarks may be words, logos or other symbols indicating that goods come from a particular company. They may even be sounds, three-dimensional symbols (such as the well-known McDonald's golden arches) or colors. There are also service marks, which indicate the source of services, and other kinds of marks that will not be considered here.

As with patents, one can infringe on another's marks without copying them or even being in direct competition with their owner. All that is necessary is to use the same or a similar mark under circumstances in which consumers may be confused as to the source or sponsorship of the goods or services.


A trademark search is the only way to find out whether Figaro or something confusingly similar is being used by others as a mark for a mousetrap (or perhaps such things as rodenticides) in the proposed market area. It is also necessary to determine whether the mark has been registered in the U.S. Patent and Trademark Office, which could give the registrant rights well beyond the market areas currently occupied.

There are two reasons why a search may not be sufficient. First, in the United States, it is unnecessary for a firm to do more than use a good mark to have trademark rights in its market area. Consequently, a search may not locate all such prior users. Second, people may be able to prevent the use of a potential mark without having used it as a mark themselves; for example, when a trademark can be associated with others in such a way that consumers might presume that some kind of relationship might exist. This is where the mark Figaro would run into trouble.

As you may recall, Figaro is the name of the cat in the Disney film Pinocchio. Although the Walt Disney Company does not have a monopoly on the use of the name, it might nevertheless be able to prevent it from being used on a mousetrap. If that seems too farfetched, consider the company's concern if "Mickey" had somehow been part of the mousetrap name!


A copyright provides an owner with the exclusive rights to reproduce a certain work for a specified period, subject to some basic limits. The term of a copyright is the lifetime of the author plus 50 years in the case of identifiable, living authors. Copyrights arise automatically and are inexpensive to register.

Searching for a prior copyright is probably unnecessary. Copyright infringement can be avoided by establishing that a work was independently created. Therefore, records showing independent creation are helpful to avoid liability. Even with such records, establishing independent creation may be difficult if the original work was widely disseminated or otherwise available to the alleged infringer. In one such case, the court held that, although copying may have been unconscious, the original was nevertheless infringed.

One of the limits to copyright protection is that ideas (compared to expressions) and technology (computer software aside) are generally not protected. This means that our inventor is free, at least as far as copyright laws are concerned, to use any information that can be found in books on mousetrap designs and to make and sell working copies of anything shown or described. Copyright gives the owner only the right to prevent reproduction of the text or drawings themselves.

What if the inventor wants to use some of that text, for example, in an advertisement? There is a remote possibility that such use might be protected under the "fair use" defense, but it would be very unwise to proceed without getting permission from the copyright holder or seeking expert advice.


Trade secrets overlap the subject matter of copyrights and patents. As long as efforts have been made to preserve secrecy, a suit may be brought to redress the misappropriation (or wrongful taking) of almost any kind of information of competitive value. Misappropriation includes industrial espionage and breaches of confidential relationships (for example, by former employees), but it does not include reverse engineering. Thus, a trade secret suit will not succeed if an aspect of a product's design or construction was obtained by examining an item purchased in the marketplace. Nor will a suit be useful against those who independently discover a secret process or recompile commercially valuable information.

The risk of being accused of misappropriating a trade secret is never very high, particularly if one seeks competent legal advice before using unlicensed information that has not been obtained through reverse engineering.


Any attorney admitted to practice in any state in the country is technically qualified to register trademarks with the U.S. Patent and Trademark Office or copyrights with the U.S. Copyright Office in Washington D.C. Unlike the situation with patents, no special examination is given to determine whether the attorney is familiar with the copyright or trademark law or registration procedures, for example. Clients are advised to seek an attorney who specializes in such matters.


Whether or not our mousetrap inventor takes measures to preserve the intellectual property, he or she certainly should avoid infringing on the rights of others. Although this is not difficult in the case of copyrights and trade secrets, patents and trademarks are another matter altogether.

Unquestionably, it costs precious start-up capital to have patent and trademark searches performed; however, proceeding in a new venture without doing so is equivalent to erecting a building or signing a long-term lease without checking the real estate title. Searches will not make the product appeal to the public, but they will ensure enjoyment of any hard-won market success. A patent search is comparatively cheap insurance against the possible need to retool or to absorb inventory losses. Moreover, a close look before adopting a trademark is cheaper in the long run than the cost of advertising and new promotions designed to advise customers to seek the mousetrap under a new name.
