Tf3 Limited v. Tre Milano, LLC, 894 F.3d 1366 (Fed. Cir. 2018).

Opinion

Newman, Circuit Judge.

TF3 Limited ("TF3") appeals the decision of the Patent Trial and Appeal Board ("PTAB" or "Board") 1 in an inter partes review of U.S. Patent No. 8,651,118 ("the '118 Patent"), requested by Tre Milano, LLC. Tre Milano challenged the validity of claims 1-5 and 11, and did not challenge the validity of claims 6-10 and 12-15 of the '118 Patent. The PTAB instituted review of all of the claims that were challenged.

We conclude that the Board erred in its finding of anticipation, for the Board erroneously construed two claim terms: "the length of hair can pass through the secondary opening" and "free end," broadening the claims beyond the description in the '118 Patent specification. On the correct claim construction, the claims are not anticipated.

*1368 I

BACKGROUND

A. The '118 Patent

The '118 Patent is for a "hair styling device" that automates the curling of hair. In operation, a strand of hair is fed into a chamber of the device, the hair is wound around a rotating curling member in the chamber, the wound hair is heated to preserve the curl, and the curled hair slides off the curling member and exits the chamber. TF3 explains that "because the secondary opening 50 is annular and surrounds elongate member 20 the length of hair is not required to pass any obstruction or otherwise be forced to uncurl during its removal from the hair styling device 10, so that the curvature of the curls created by the device can be substantially maintained." '118 Patent, col. 6, ll. 39-44.

Figures 1 and 2 show the claim elements related to this appeal: the elongate member 20, primary opening 24, secondary opening 50, and movable abutment 52:

In operation the device receives a section of hair 26 through primary opening 24 into chamber 16. A motor-driven rotatable element 34 rotates and its leading edge 38 engages and captures the hair 26. The rotating element winds the hair around elongate member 20 until it reaches abutment 52. The abutment prevents twisting of the hair by stopping the hair from rotating around the free end of the elongate member 20. The wound hair is then heated. The user then releases the grip on handle parts 60 and 62, see Fig. 2, automatically moving abutment 52 from its closed position to its open position, and releasing the curled hair through the second opening 50.

Claim 1 is deemed representative:

1. A hair styling device having:
a body defining a chamber adapted to accommodate a length of hair, the chamber having a primary opening through *1369 which the length of hair may pass into the chamber;
a rotatable element adapted to engage the length of hair adjacent to the primary opening;
an elongate member around which, in use, the length of hair is wound by the rotatable element, the elongate member having a free end;
the chamber having a secondary opening through which the length of hair may pass out of the chamber, the secondary opening being located adjacent to the free end; and
a movable abutment which can engage the length of hair in use, the movable abutment having an open position in which the length of hair can pass through the secondary opening, and a closed position in which the length of hair is retained within the chamber, wherein the moveable abutment is located within one of (i) the secondary opening, (ii) the primary opening, and (iii) a passageway connecting the secondary opening to the primary opening.

Dependent claims 2-5 and 11 add limitations specifying the position of the movable abutment and the shape of the secondary opening.

B. The Prior Art

The Board instituted review on two grounds: anticipation by U.S. Patent No. 4,148,330 ("Gnaga") and/or anticipation by Japanese Patent Application No. 61-10102 ("Hoshino").

The Gnaga reference, titled "Motor-Curler Unit for Automatic Application of Curlers to the Hair to be Treated," shows a hair-curling device in which curler A, composed of internal portion B and external portion C, is inserted into the device at housing D. The hair is wound around the rotating curler and heated, and the curler carrying the hair is ejected and disassembled, allowing removal of the hair by unwinding from the curler. Figures 6 and 7 depict the Gnaga device:

Gnaga, Figs. 6, 7.

The Hoshino reference describes a hair-curling device in which a curler is inserted *1370 into a winding structure, hair is wound around the rotating curler, supported by a lock lever and hair guide arm, and then the curler carrying the hair is ejected from the device and disassembled, allowing removal of the curl by unwinding from the curler. J.A. 631 (Hoshino Translation). Hoshino Figures 1 and 2 illustrate the device, including curling member 9, lock lever 25, and hair guide arm 16.

Hoshino, Figs. 1, 2.

C. The Board Decision

The Board held that Gnaga and Hoshino each shows the same device as claimed in the '118 Patent, rendering the claims invalid for anticipation. However, as is apparent, the devices are not the same. Anticipation was decided on a flawed analysis, whereby the '118 Patent claims were construed to have a breadth beyond the scope supported by the device described in the '118 Patent, the Board then holding that the unduly broad '118 Patent claims read on the different Gnaga and Hoshino devices and thus are anticipated.

The Board construed "free end" to mean "an end of the elongate member that is unsupported when the movable abutment is in the open position." Board Op. at *13. The Board rejected TF3's proposed construction of "the length of hair can pass through the secondary opening" to mean "when the abutment is in its open position, the styled length of hair is allowed to slide along the elongate member towards and subsequently off its free end," id ., instead determining that claim 1 "does not require *1371 that the length of hair is allowed to slide along the elongate member towards and subsequently off its free end." Id . at *16.
