A design patent search involves searching existing patents to make sure your design has not already been patented. A design patent is available for original, new, and ornamental designs for an item. It allows an investor to create a new way to design an existing product. The design patent protects the unique design without changing the patent on the item. A design patent protects only the appearance of the article and not structural or utility features.
Before filing a design patent, it is preferable to go for a design patent search because it can save the investment or expenses of an inventor on the subject product design. It also allows the investor to make some modifications in the working stage which is beneficial in getting patents.
