  • Intellectual Property Outlook: Cases and Trends to Follow in 2012
    February 2012 Intellectual Property Outlook: Cases and Trends to Follow in 2012 BY ROBERT M. MASTERS, TAD RICHMAN, & LISA LEUNG I. Introduction In the coming year, we anticipate a series of events and decisions with varying degrees of impact on intellectual property law in the United States and, in turn, the way we advise our clients. This article highlights cases we are monitoring that present, in our view, significant issues relating to various aspects of intellectual property law. Most of these cases are pending appeal at some level, and each has the potential for considerable impact on the landscape of U.S. intellectual property law. A small number of recently decided cases have also been selected for inclusion in this discussion, as it remains to be seen precisely how these decisions will play out in practice over the coming year. Lastly, we take a look at continuing trends in the intellectual property marketplace and review key legislation, including what to expect from the recently enacted America Invents Act. II. Cases to Watch in 2012 A. The Scope of Patentable Subject Matter 1. Medical Diagnostic and Treatment Methods Post-Bilski The Supreme Court heard oral argument in Mayo Collaborative Svcs. v. Prometheus Labs., Inc., No. 10-1150, on December 7, 2011. This is not the first time the Supreme Court has taken on the question of the validity of Prometheus’s asserted method claims. As before, Mayo challenges the Federal Circuit’s holding that Prometheus’s method claims recite patentable subject matter under §101. Unlike before, Mayo’s appeal now derives from a post-Bilski decision below.1 Prometheus is the sole and exclusive licensee of two patents claiming methods for determining the optimal dosage of thiopurine drugs used to treat certain autoimmune diseases.

  • Structure and Function of the Patent Specification August 2014
    Structure and Function of the Patent Specification August 2014 Structure and Function of the Patent Specification The structure of a patent specification is described below, with some explanations of underlying patent law concepts that the specification is designed to address. At the end of this note is a section which guides applicants in checking a specification that we prepare on their behalf. General Purpose The purpose of the patent specification is to fulfil the patentee’s part in the contract that a patent constitutes. In return for a full disclosure of the invention, the patentee can have a time-limited monopoly for the invention. During that time, the patentee has the right to stop others working the invention without permission. The monopoly generally lasts for twenty years, although annual renewal fees are usually payable. After the patent expires, the invention enters the public domain and cannot be patented again. A patent is enforced if necessary against infringers by action brought before the court. A patent specification is a legal document. Third parties and the court must be able to understand it, so that the limits of the protection it affords can be determined precisely. Structure of the specification • A patent specification normally has the following parts in the order given: • A title to identify the invention. • A statement as to the field to which the invention relates. • An explanation of the background “state of the art” – what was already known prior to the invention. • A statement of an objective technical problem which the invention seeks to solve, or an objective the invention is aimed at achieving.

  • Preparation and Filing of a Provisional Patent Application I
    i Preparation and Filing of a Provisional Patent Application Introduction A provisional application is a means for inventors to easily, quickly and inexpensively obtain “patent pending” status and establish a priority date in the United States Patent and Trademark Office. The provisional application has a one year term. Prior to the expiration of the provisional, a regular utility patent application must be filed which claims priority to the earlier filing date of the provisional. The provisional application is usually less expensive since all of the formal requirements that are needed for a regular utility patent application are not required. In addition, there is no requirement to include write “claims” for the invention. While the claims are important to ultimately define the scope of the invention, preparation of valid claims can be the most difficult section for the lay person to prepare. To the untrained eye, the claims sometimes appear to include highly technical jargon written in a foreign language. But the legal requirements of defining the metes and bounds of an invention require a high degree of precision which is not always easily expressed in plain language. Assuming that the same subject matter of the utility application is included in the provisional application, it is as if the utility application was filed as of the earlier provisional date. This is important since the first to file will typically be considered the first inventor. Note that the provisional priority date only applies for material included in the provisional application. Thus, details are important! During this one year period, the inventor can investigate the commercial feasibility of the invention to determine if the cost of a regular patent application is worth the expense.

Patent portfolio INTRODUCTION The term "intellectual property (IP)" is defined as the property resulting from creations of the human mind, the intellect. In this regard, it is fair that the person making efforts for an intellectual creation has some benefit as a result of this endeavor. Probably, the most important among intellectual properties is “patent.” A patent is an exclusive right granted by a government for an invention, which is a product or a process that provides, in general, a new way of doing something, or offers a new technical solution to a problem. The details on the way of acquiring patents will be provided for protecting precious intellectual properties. LEARNING OBJECTIVES 1. You understand how to decide whether your new technology or invention should be protected by one or more patents and, if so, how to do so. 2. You know how the grant of a patent over an invention or technology helps you to prevent or have an upper hand in legal disputes that may arise later on.

  • Preparing-A-Patent-Application.Pdf
    PREPARING A PATENT APPLICATION Patentability 1. The idea, concept or device must be novel. It cannot have been publicly known anywhere in the world prior to its invention by you. Public disclosure includes publication, display, presentation, offer for sale, commercial use or inclusion in a previous patent. 2. The invention must be kept confidential. In the United States a patent application can be filed one year from the date you publicly disclose, BUT in the rest of the world, the right to file is lost the day it is disclosed. Therefore, it is important to contact the Technology Transfer office before making any public disclosure. 3. The invention must not be obvious. An argument must be made that an average person who is skilled in the field would not have thought of the invention as an obvious extension or combination of existing knowledge. This is the most difficult test because the patent examiner can argue that IF a person knew about A, B and C they could have arrived at X. 4. Inventions which are NOT patentable include theories, plans of action, mental processes, laws of nature, mathematical expressions or algorithms, methods of doing business or naturally occurring substances (although their isolation or use may be patentable). General Considerations 1. A patent application is divided into two distinct parts. Disclosure or Specification -- The disclosure comprises the bulk of the patent application. It includes a discussion of all related literature, patents and publicly disclosed material. It contains a detailed explanation of the invention and how it differs from all prior public matter, and it describes the best mode of practicing the invention in enough detail that an average person skilled in the field could reproduce the invention.
