In a federal lawsuit filed last week in California, Shelly Conty and Cindy Reichman allege that Hide ‘N Seek Secret Bear and Hide ‘N Seek Surprise Bear violate US Patent 6,494,457 which is titled “Enhanced hide and seek game and method of playing game.”

The women say the patent protects their own toy, named Hide ‘N Seek Hayley, and want toy-maker Jakks Pacific to hand over triple damages and to stop making the Care Bears in question.

According to their lawyer, Lenden Webb, the women “invented, marketed, produced and sold” an idea and now the Care Bears have “stolen what they’ve done.”

Webb says the invention covered by the patent is useful because it “enables a kid to have a bear hid by an adult.” The new method of hide and seek, which can be seen in a diagram here, involves a transmitter placed inside the toy and a receiver that says if the child is getting closer.

“The participant interacts with the seeker unit to use and develop his or her logical reasoning skills in searching for the hidden object,” says the patent.

In recent years, critics have said the U.S. Patent and Trademark Office has been too quick to grant patents for seemingly obvious inventions, especially those involving so-called business methods. Famous examples include Amazon’s “one-click patent” and one granted to a five-year old for a method of swinging on a swing. Last year, President Obama signed a major patent reform bill but many of the changes it contains will only affect new patents.

Webb says Hide ‘N Seek Hayley is no longer available for sale. The Care Bears appear to be available on Amazon (NSDQ: AMZN) where parents have given them mixed reviews.

Jakks Pacific, which also makes Cabbage Patch Kids, Pokemon and other toys, didn’t return a request for comment.
