Famous Toy Trademarks & Patents

Tinker Toys, the Easy Bake Oven, Cabbage Patch Dolls–most adults fondly remember the toys of their childhood. Many, inspired by their own children, dreams of “the toy they always wanted”, or visions of fame and fortune attempt the formidable leap from ordinary citizen to toy inventor. What, at first glance, might appear to be a relatively simple process is, in fact, a labyrinth of research and documentation requiring tenacity and diligence. For toy designers, the thrill of creating something exciting to share with others is tempered by the reality that the toy industry comprises a market of $21.2 billion in the United States alone. Large toy manufacturers routinely file lawsuits against each other in an attempt to protect their unique products and designs, and, ultimately, their piece of the financial pie. Amateur toy designers can increase their odds of protecting their original ideas and shield themselves from lawsuits by devoting a significant amount of time to studying and implementing an understanding of patents and trademarks.

Patent and trademark laws and processes vary according to country. In the US, the Patent and Trademark Office (USPTO) is responsible for issuing patents and trademarks. A patent protects an inventor’s right to manufacture and sell an invention and prevents others from selling the same product. Trademarks protect a distinguishing “word, phrase, symbol, and/or design” (USPTO) associated with a particular product.

While obtaining patents and trademarks is a time-consuming and complicated process, inventors can do some of the initial legwork and research on their own before hiring a patent attorney. The Inventors Assistance Center (IAC), a branch of the USPTO that assists inventors from the general public, strongly recommends keeping a dedicated bound notebook containing sketches, research, etc. for each idea that will serve as a legal record throughout the design, patenting, and production process. Existing patents can be searched online through the USPTO database or Google’s recent collaboration with the USPTO.

After the initial research and discovery phase, the IAC recommends filing a provisional patent application that holds the design idea as the inventor’s intellectual property for one year. Provisional applications do not go through the official patent examination process, but they do establish an earliest filing date and allow the term “patent pending” to be included with information about the design as the inventor presents their idea to toy companies or searches for financial backers. Before the provisional term ends, a non-provisional application must be filed. To protect the entire design, inventors will need to consider filing non-provisional applications for both a utility (how something works) patent and a design (how something looks) patent. Non-provisional utility patents have a term of 20 years and design patents last for 14 years. Once the non-provisional applications have been filed the patent examination and approval process takes, depending on the type of product, an average of 32 months. It is also important to explore the necessity of filing patents in other countries; that process can be streamlined through the Patent Cooperation Treaty system.

Thoroughness during the patenting process can establish the longevity and success of a product far into the future. LEGO, twice named “Toy of the Century” in 2000, is arguably the most-loved, most-recognizable toy in the world. Understandably, LEGO Group devotes massive amounts of time and money to protect its patents and trademarks that cover its broad catalog of products. LEGO had humble beginnings in 1932 under the leadership of Danish carpenter Ole Kirk Christiansen, but quickly developed innovative products thanks to the ideas of Christiansen’s son, Godtfred Kirk Christiansen.

Although the company adopted the name “LEGO” (from “leg godt”- Danish for “play well”) in 1934, it did not officially register a trademark until 1954. As the company moved from wooden toys to plastic, the distinctive LEGO coupling system was patented in 1958. The brand expanded exponentially throughout the years with the addition of DUPLO, LEGOLAND theme parks, retail stores, books, and video games, as well as licensing partnerships with companies like Disney and Pixar.

Being an international toy powerhouse does not guarantee immunity from companies who try to profit from your original ideas or patents. Since LEGO’s patents began expiring over 20 years ago, they have been involved in numerous lawsuits, particularly with Mega Blocks and Best-Lock – two competitors that produce blocks with striking similarities to the Danish blocks. The company website even contains explicit directions regarding the use of its logo and other trademarks on LEGO fan-based websites. Recently, LEGO has lost most of its court battles, and the company’s origins have been tainted by the revelation that Ole Christiansen got the idea for the now-famous interlocking blocks from British psychologist Hilary Page who passed his sketches and prototypes on to Christiansen. Despite these setbacks, LEGO continues to lead the way in toy innovation; at the February 2013 American International Toy Fair, LEGO debuted 250 new building sets.

Navigating the waters of toy development is not for the faint of heart. Luckily, numerous quality resources exist for those interested in bringing their creative ideas to fruition. Meticulous research and detailed record keeping, as well as the tenacity to follow through on an idea just might net you a place in the National Toy Hall of Fame. If you have a toy dream, see it through to the finish!
