Before bringing a new product to market, a certain amount of due diligence is recommended.
For example, before marketing a product or service; whether a financial product, a toy, a new restaurant, mobile phone app or anything else, it is recommended that you conduct a search of the records of the U.S. Patent and Trademark Office to make sure that no one has registered that product or service name or mark or a confusingly similar mark for the same or similar products or services. See http://www.uspto.gov/trademarks-application-process/search-trademark-database
If a logo is a critical part of that mark, the U.S. Patent and Trademark Office database should be searched for similar designs which may be claimed by a potential Plaintiff as a basis for an assertion that in commencing the use of your design you have infringed its design.
Google’s search engine may be utilized as well as registration is not a prerequisite for asserting trademark rights in the U.S.
It is, of course, recommended that you secure the services of experienced trademark counsel and have experienced trademark counsel conduct that search as experienced trademark counsel should be familiar with the relevant case law and, therefore, be able to determine the likelihood that a court would consider your proposed name to be a violation of another party’s rights.
If you have an invention, whether it be a Process, namely a mode of treatment of certain materials to produce a given result, a Machine, namely a concrete thing, consisting of parts, or of certain devices and combination of devices intended to perform some function and produce a certain effect or result, an article of Manufacture, namely an article produced from raw or prepared materials by giving to these materials new forms, qualities, properties, or combinations, whether by hand labor or by machinery or a Composition of matter, namely compositions of two or more substances and all composite articles, whether they be the results of chemical union, or of mechanical mixture, or whether they be gases, fluids, powders or solids, then you could have patentable subject matter (See https://www.uspto.gov/web/offices/pac/mpep/s2106.html) and should, again, conduct a search to ensure that that subject matter of your invention does not involve the making, using, selling, or offering to sell another’s invention which is the subject of prior and currently active patent protection.
Again, as with trademarks, there are databases that are available to begin that search. For example, you can search the U.S. Patent and Trademark Office’s database for patents assigned to your competitors or patents with titles that suggest the subject matter of your invention. You can also search https://scholar.google.com/ for relevant patents to your invention.
However, note here that I do not practice Patent Law and therefore recommend that you secure the services of an experienced patent attorney who can conduct that search and who would be familiar with the relevant case law as to what constitutes patentable subject matter as well as, through his or her knowledge of the relevant technology, could determine whether your invention would be a violation of another party’s rights.
If your invention constitutes patentable subject matter or your brand name is available for protection in the U.S. Patent & Trademark Office, or if, you are offering your product or services to customers outside the United States, available for protection in the relevant trademark and patent offices of those other countries in which you are doing business I strongly recommend that you protect that subject matter or name with that Office and offices.
Copyrights are another story, however. The Stanford University Libraries have put out a handy little guide on searching the records of the Copyright Office. See http://fairuse.stanford.edu/overview/copyright-research/searching-records/ Herein, lies the due diligence problem. The Copyright Office database will provide you with an often vague title of a work, the copyright claimant, the date the Copyright Registration was effective, the date of creation of the copyrighted article, the date of publication of the article, i.e., the distribution of copies or phonorecords of a work to the public by sale or other transfer of ownership, or by rental, lease, or lending and the name of the author but it won’t provide you with an image of what was deposited with the application for Copyright Registration. Without that image, there is no way to determine if what you have created is a copy of a protected work. While Copyright Infringement requires not just that your work and the copyrighted work be substantially similar but that you had access to that work in creating your own, i.e., you copied the other party’s work, there may be circumstances where your lack of access to the similar work may not protect you from an infringement claim. See, for example, Selle v. Gibb, 741 F.2d 896, 901 (1984) where the federal Seventh Circuit Court of Appeals wrote, “If, however, the plaintiff does not have direct evidence of access, then an inference of access may still be established circumstantially by proof of similarity which is so striking that the possibilities of independent creation, coincidence and prior common source are, as a practical matter, precluded. If the plaintiff presents evidence of striking similarity sufficient to raise an inference of access, then copying is presumably proved simultaneously, although the fourth element (substantial similarity) still requires proof that the defendant copied a substantial amount of the complaining work.”
Herein lies the due diligence problem. Since everything from advertisements to maps to bumper stickers to dolls to toys to wall-covering designs to games to greeting cards to jewelry designs to posters to photographs to sculptures to architectural plans to computer software and any graphics generated thereby may be the subject of copyright, how can you tell if your product is not a copy of something that’s already out there. See http://www.copyright.gov/circs/circ40.pdf You can search the relevant marketplace, either in its bricks and mortar form or its on-line form but then you can only make an educated guess that any similar product out there is the subject of a copyright registration. Of course, if the brand name of the similar product is identical to its title in the Copyright Office database and the ownership of the product is the same both in that database and on the product’s packaging I would be careful, as that would be a good sign that your product may be the subject of someone’s copyright claim and I would make sure that the products were not substantially similar. Again, here I would recommend that an experienced copyright lawyer compare the two products and assess the validity of the potential copyright claim. But all you would have is an educated guess. To view the actual game, toy, photograph, software or jewelry design that is the subject of that copyright claim, your request for copies of deposits should be submitted to the Records Research and Certification Section. Note that the Copyright Office does not retain all works deposited for copyright registration. Also note that that Office will provide certified or uncertified copies of published or unpublished works deposited in connection with a copyright registration and held in the Office’s custody only when one of the following three conditions has been met:
(1) Written authorization is received from the copyright claimant of record or the owner of any of the exclusive rights in the copyright, as long as this ownership can be demonstrated by written documentation of the transfer of ownership.
(2) The Copyright Office Litigation Statement Form is completed and received from an attorney or authorized representative in connection with litigation, actual or prospective, involving the copyrighted work. The following information must be included in such a request: (a) the names of all parties involved and the nature of the controversy, and (b) the name of the court in which the actual case is pending. In the case of a prospective proceeding, the requestor must give a full statement of the facts of controversy in which the copyrighted work is involved, attach any letter or other document that supports the claim that litigation may be instituted, and make satisfactory assurance that the requested reproduction will be used only in connection with the specified litigation.
(3) A court order is issued for a reproduction of a deposited article, facsimile, or identifying portion of a work that is the subject of litigation in its jurisdiction. The order must be issued by a court having jurisdiction over a case in which the copy is to be submitted as evidence. A request for copies of works deposited in connection
with a copyright claim should be accompanied by whatever material is necessary to show that one of the three conditions given above has been met.
So while due diligence is always recommended, conducting the necessary due diligence may not be easy or cheap.
