Sample Work

Our patent attorney has secured numerous inventions for our clients.
Any result the attorney or firm may have achieved on behalf of a client does not necessarily indicate similar results can be obtained for other clients.

Our trademark and patent attorney assists clients with utility (provisional/non-provisional) patent applications, international applications, trademarks, responding/ formulating cease and desist letters, and other litigation related matters. We can help you strategize your patent portfolio according to your business needs. The USPTO provides a flow chart of the over all process.
A provisional patent application is a temporary application filed with the USPTO expiring within 1 year. Provisional patent applications are not examined by the USPTO and are held in confidence. Prior to the expiration of the provisional patent application, you will need to file a non-provisional patent application to initiate the examination process.
A trademark, trade mark, or trade-mark is a recognizable sign, design or expression which identifies products or services of a particular source from those of others. The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, a voucher or on the product itself. For the sake of corporate identity trademarks are also being displayed on company buildings. A trademark must be used in commerce.
A non-provisional application is a request pending at a patent office for the grant of a patent for the invention described and claimed by that application. A non-provisional application can claim priority from a filing date of a provisional application. The non-provisional application consists of a detailed description (patent specification), formal drawings, and claims together with official forms and correspondence relating to the application. It is important that the non-provisional application is crafted well as this document can eventually yield a patent.
A design patent is a form of legal protection granted to the ornamental design of a functional item. Design patents are a type of industrial design right. Ornamental designs of jewellery, furniture, beverage containers and computer icons are examples of objects that are covered by design patents. It is important that you contact your patent attorney and inquire if a design patent can further secure your IP rights.
