In Broadsoft, Inc. v. Callwave Communications, LLC, a three-judge Federal Circuit panel issued a per-curiam decision affirming the United States District Court for the District of Delaware’s grant of a motion for judgment on the pleadings as to patent ineligibility under 35 U.S.C. § 101. The trial court’s order examined claims in two patents assigned to Callwave Communications, U.S. Patent Nos. 8,351,591 and 7,822,188. The trial court found that the claims covered telephony methods involving conventional elements and lacking an inventive concept.
instructing the call processing system to connect the first call to a third communication device.
causing the second call and the second outcall to be bridged.
Broadsoft filed a declaratory judgment action in the United States District Court for the District of Delaware seeking declaratory judgment that claims in Callwave’s patents were invalid. Callwave’s patents came under attack from Broadsoft after Callwave asserted those patents against Telovations, Inc., which had licensed accused software products from Broadsoft, and Bright House Networks, LLC, which had acquired Telovations. The software license agreement between Broadsoft and Telovations specified that Broadsoft owed an obligation to defend Telovations against patent infringement claims based on the software.
Broadsoft submitted motions seeking judgments that Callwave’s ’591 and ’188 patents were directed to patent ineligible subject matter under § 101. The motions also argued that the patents were invalid as anticipated under § 102 and obvious under 35 U.S.C. § 103.
Broadsoft argued that the idea of sequentially dialing a list of telephone numbers is an abstract idea that fails to provide any improvement to computer or technological processes. According to Broadsoft, the claims simply identify steps that automate the task of accessing a list of telephone numbers and sequentially dialing them, a task previously performed manually by a human. Callwave countered that the claims allow a call to be redirected without hanging up and redialing, a process impossible for a human operator who does not know any additional phone numbers for the party being called.
The court agreed with Broadsoft’s arguments, and found the sequential dialing claims were directed to an abstract idea. The court noted that the problem of callers receiving busy signals or being sent to voicemail rather than reaching the called party was a “human unavailability problem” that was not specific to telephone technology.
Broadsoft also argued that the sequential dialing claims lacked an inventive concept, partly because they simply use computer telephony to implement the idea of sequential dialing, and because no inventive concept is conveyed in claims that narrow an abstract idea to a particular technological application. Callwave cited McRo, Inc. v. Bandai Namco Games America, Inc., and argued that its claims did identify an inventive concept, focusing on three limitations addressing: 1) internet protocol proxy messaging for receiving or placing calls, 2) use of timing or number of rings to determine when to place a second call, and 3) use of a hybrid network to handle calls from different interfaces by converting call protocols.
The single number outcall claims similarly identified an abstract idea and failed to include an inventive concept. The court found that exemplary claim 1 was essentially “directed to storing data in a database, looking up data from that database in response to the initiation of a phone call, and inserting at least a portion of that data in the already-existing callerID field,” and concluded that the “problem of being unable to reach a particular individual is a practical, human unavailability problem, not a technological one.” The court also noted that the claims could be practiced in an office setting by a human assistant. The court found no improvement to telephony technology or solution to a specific phone problem.
The Federal Circuit panel’s per curiam affirmance leaves Callwave with the option to request rehearing by the panel or the Federal Circuit as a whole en banc. Callwave has 30 days from the date of the opinion, or until November 16, 2018, to submit a petition for rehearing by the panel or rehearing en banc.
The trial court’s decision occurred before Berkheimer v. HP, Inc., which generally states that factual issues may prevent a grant of judgment on the pleadings as to patent eligibility under § 101. But the Federal Circuit’s post-Berkheimer affirmance here indicates its agreement with the trial court’s conclusion that no such factual issues existed. Notably, the trial court’s decision finds absence of any factual issues as to whether an Internet Protocol proxy server, Session Internet Protocol proxy and computer telephony system are “conventional” elements. The trial court also determined that the problem the claims attempt to solve is that of a caller having to hang up and redial a new number if they get a busy signal or reach voicemail, which the court found is a “human unavailability problem,” not a technical one. Without contradictory evidence to consider, a court may find a lack of factual issues as to patent eligibility when the patent’s specification describes technology as “standard” or “conventional” and the claims identify a problem that can be solved by adding a human actor.
