Los Angeles, CA (Law Firm Newswire) February 4, 2014 — Patent applications that describe more than one invention may face challenges in the United States Patent and Trademark Office (USPTO).
Inventors generally pursue separate patents for separate inventions. But when the inventions and their claims are closely related, the inventor may instead pursue a single patent with a single application. As a local patent prosecution attorney explains, that strategy is not always permitted by the USPTO.
“When a USPTO patent examiner determines that a patent application contains claims defining two or more distinct inventions, the office may issue a restriction requirement,” said Simi Valley patent attorney Pejman “PJ” Yedidsion. “The applicant will then be required to choose which invention to pursue in the current application.”
Patents on the remaining invention(s) may then be pursued in one or more divisional patent applications. “Divisionals,” as they are often called, are a type of continuation application. They generally have the same specification, or written description, of an invention and claim the priority date of their parent application, but they contain separate claims.
The Manual of Patent Examination Procedure (MPEP), Chapter 803, lists two criteria necessary before a restriction requirement may be issued. First, the inventions in the application must be independent or distinct as claimed. Second, the application must present a “serious burden” to the examiner if restriction is not required.
Restriction requirements narrow the scope of the patent application in question. Additionally, they increase the cost in time and fees of obtaining patent protection for all of an inventor’s claims. In some cases, obtaining protection on all claims will prove impractical or infeasible. On the other hand, obtaining separate patents for related inventions may be advantageous in some cases.
“If an inventor presented with a restriction requirement believes that the examiner has failed to establish that a serious burden exists without the restriction, the inventor may contest the requirement on those grounds,” Yedidsion added. “In that case, the counsel of an experienced patent prosecution attorney is essential.”

- SUPREME COURT TO DECIDE WHETHER COMPUTER-IMPLEMENTED INVENTIONS CAN BE PATENTED
Are computer-implemented inventions directed to patent eligible subject matter? This question is now before the Supreme Court in Alice Corporation v. CLS Bank Intl. Oral arguments are set for March 31 and the decision is expected in June 2014.<br />

- Speedy Patent Prosecution, Part 2: Accelerated Examination
