2 ORTHOACCEL TECHNOLOGIES, INC. v. PROPEL ORTHODONTICS, LLC

Before PROST, Chief Judge, REYNA and WALLACH, Circuit Judges.

REYNA, Circuit Judge.

OrthoAccel Technologies, Inc. appeals from a decision of the U.S. District Court for the Northern District of California denying its motion for a preliminary injunction. The district court determined that the patent at issue could not claim priority to its parent application because the parent application lacked written description support for the claimed “1 to 20 minutes daily” limitation. On this basis, the district court determined that OrthoAccel Technologies , Inc. was unlikely to demonstrate at trial that the patent at issue was not anticipated by its parent application and denied the preliminary injunction. Because we conclude for the reasons below that the district court did not abuse its discretion, we affirm.

BACKGROUND I. The ’184 Patent OrthoAccel Technologies, Inc. (“OrthoAccel”) is the assignee of U.S. Patent No. 9,662,184 (“the ’184 patent”), entitled “Vibrating Dental Devices.” The ’184 patent is directed to a method for providing accelerated tooth movement using a vibrating dental device for persons undergoing traditional orthodontic treatment. ’184 patent, Abstract, col. 1 ll. 24–25. The ’184 patent discloses that it was well known in the field of orthodontics that “a pulsating force” could be employed “to move teeth more rapidly and to ease the discomfort of traditional orthodontics.” Id. col. 1 ll. 44–46. The ’184 patent explains that prior art devices , however, were “bulky,” “expensive,” and “very difficult to use.” Id. col. 1 l. 66–col. 2 l. 3. The ’184 patent attempts to solve these problems by providing a method of using an improved vibrating device with an intraoral U-

shaped plate and an extraoral vibrating actuator. Id. col. 2 ll. 63–64, col. 14 ll. 1–20. The ’184 patent discloses “applying differential vibration to selected areas of a bite plate . . . for a period of 1–60 minutes, preferably about 1– 30 or 1–10 minutes or 20 minutes.” Id. col. 7 ll. 33–38.

Independent claim 10 of the ’184 patent is at issue in this appeal and recites:

A faster method of orthodontic remodeling, comprising :

a) a patient wearing an orthodontic appliance biting an orthodontic remodeling device , said orthodontic device comprising:

i. an extraoral housing containing a power source operably coupled to an actuator operably coupled to a processor that controls said actuator ; and ii. said extraoral housing operably connected to an intraoral U-shaped bite plate; iii. wherein during use said orthodontic remodeling device is held in place only by teeth clamping on the bite plate and said orthodontic remodeling device vibrates at a frequency from 0.1 to 400 Hz; and b) activating said orthodontic remodeling device for 1 to 20 minutes daily; wherein said method provides accelerated tooth movement as compared to without using said orthodontic remodeling device.

Id. col. 14 ll. 1–20 (emphasis added).

The application that led to the ’184 patent claims priority to a series of applications starting with U.S. Provisional Application No. 60/906,807, filed on March 14, 2007 (“the provisional application”). The provisional application led to non-provisional U.S. Application No. 11/773,849, filed on July 5, 2007, and published on September 14, 2008 (“the parent application”). U.S. Application No. 12/615,049 is a continuation-in-part of the parent application and was filed on November 9, 2009, more than one year after publication of the parent application (“the CIP application”). The CIP application was followed by two parallel continuation applications, and then the continuation application from which the ’184 patent issued.

Both the provisional application and the parent application disclose only that OrthoAccel’s vibrating device should be worn for “approximately” or “about” twenty minutes per day. J.A. 578, 609, 614. Both of these applications also disclose that “longer or shorter” time periods or “any other suitable duration of time” may be used, but do not expressly disclose any other specific period of time. J.A. 578–79, 609. The CIP application first introduced time periods other than “about” 20 minutes, disclosing the same durations of “1–60 minutes, preferably about 1–30 or 1–10 minutes or 20 minutes” as the ’184 patent. J.A. 661–62.

II. District Court Proceedings On July 4, 2017, OrthoAccel brought suit against Propel Orthodontics, LLC and Propel Orthodontics USA, LLC (collectively, “Propel”) for infringement of claim 10 of the ’184 patent. On August 18, 2017, OrthoAccel filed a motion for a preliminary injunction. Propel opposed the motion, arguing that a preliminary injunction was not warranted because claim 10 of the ’184 patent was invalid under 35

U.S.C. § 102(b)1 as anticipated by the parent application. Propel further argued that claim 10 was not entitled to claim priority to the parent application because the “1–20 minutes daily” limitation was new matter introduced in the CIP application and not supported by the parent application . 2 In reply, OrthoAccel conceded that the parent application discloses every limitation of claim 10 and was published more than one year prior to the filing date of the application that led to the ’184 patent, thus making it anticipatory prior art under § 102(b). J.A. 1213 n.1. The invalidity issue thus turned on the question of priority. J.A. 24.

Finding that Propel raised a substantial question of validity with respect to the ’184 patent, the district court determined that the burden at the preliminary injunction stage was on OrthoAccel to demonstrate a likelihood of succeeding at trial on the validity issue. J.A. 21, 25. The district court found that OrthoAccel did not meet this burden, explaining that the disclosures in the provisional and

1 Section 102(b) was amended by the Leahy–Smith America Invents Act (“AIA”). See Pub. L. No. 112–29, § 3(c), 125 Stat. 284, 287 (2011). Because the ’184 patent has an effective filing date prior to March 16, 2013, the effective date of the AIA, the pre-AIA version of § 102(b) applies . Pre-AIA § 102(b) provided that “[a] person shall be entitled to a patent unless . . . the invention was patented or described in a printed publication in this or a foreign country . . . more than one year prior to the date of the application for patent in the United States.” 35 U.S.C. § 102(b) (2006).

2 Propel also argued that a preliminary injunction should not be granted because OrthoAccel was unlikely to succeed in proving infringement. J.A. 22–23, 418–19. The district court’s rulings on the subject of infringement, however , are not at issue on appeal.

parent applications of “using time periods somewhat longer or shorter than 20 minutes carry no hint that time periods as short as a minute or two might suffice.” Id.
