PTAB: Munchkin v. Luv N'Care - Final Decision in IPR

May 1, 2014
On April 21, 2014 the USPTO’s Patent Trial and Appeal Board issued a final written decision in Munchkin Inc. et al. v. Luv N’ Care Ltd. (IPR2013-00072), the inter partes review of Luv N’ Care Ltd.’s design patent for a baby drinking cup.

The PTAB found Luv N’ Care Ltd.’s D 617,465 patent (the ’465 patent) unpatentable. This is the first time that the USPTO hasinvalidated a design patent under a post-grant review process created by the America Invents Act.

The ‘465 patent claims a drinking cup. Figures 2 and 3 are reproduced below.



In January 2012, Luv N’ Care filed an infringement suit for the ’465 patent in the Southern District of New York, against Toys R Us and Munchkin (NYSD-2-12-cv-00228).

In the complaint, Luv N’ Care stated that it had “generated hundreds of millions of dollars in revenue from the sale of goods under their trademarks and trade dress,” and that a series of competitors had allegedly “all deliberately copied [Luv N’ Care’s] designs, to illegally profit from them.”

Luv N’ Care sued the Defendants on counts of alleged infringement, trade dress infringement and unfair competition, federal trademark dilution, unfair competition under New York law, violation of New York general business law, and contributory infringement.

The ‘465 patent was also involved in the Luv N’ Care Ltd v. Regent Baby Products Corp, 10-9492 (S.D.N.Y filed Dec. 21, 2010), and Luv N’ Care Ltd v. Royal King Infant Prod’s Co. Ltd, 10-cv-00461 (E.D. Tex. Filed Nov. 4, 2010). Luv N’ Care settled with Royal King Infant Prod’s Co. Ltd, with Royal King agreeing to cease and desist from manufacture and sales of products likely to cause confusion.

In December 2012, Toys R Us and Munchkin (‘the Petitioners’) filed a petition for inter partes review, alleging that the ’465 patent was obvious in view of two references, US 2007/0221604 (the ’604 reference) and US 6,994,225 (the ’225 reference). This was the first inter partes review initiated by the USPTO for a design patent. 

The Patent and Trials Appeal Board (PTAB) determined that there was reasonable likelihood that the claim of the ‘465 patent would have been obvious over each of the ‘225 and ‘604 reference, and granted the petition for review.

First, Luv N’ Care argued that its ‘465 patent was entitled to an earlier effective filing date of US Application No. 10/536,106 (the ‘106 application), thereby disqualifying the ‘225 and ‘604 references. In response, the Petitioners argued that the ‘106 application lacked written description support for the ‘465 patent, based on differences in the spout.

Figures from both the ‘465 patent and the ‘106 application are shown below, as reproduced from the PTAB’s final written decision:



In its written decision, the PTAB stated the following differences “(1) the outer boundary of the spout tip of the claimed design is larger than that of the ‘106 application. … (2) the spout tip of the claimed design has a different, more rounded, oval shape than that of the racetrack shape of the spout tip in the ‘106 application; and (3) the spout tip of the claimed design has three concentric rings that the ‘106 application does not disclose.”

The PTAB further noted that although the ‘106 application stated that an oval or other shape may be used for the spout, the ‘106 application did not “identify the specific shape of the spout in the claimed design, or otherwise reasonably convey to those skilled in the art that the inventor had possession of the claimed design.” Accordingly the PTAB concluded that the ‘465 patent was not entitled to the filing date of the ‘106 application. The written decision notes that counsel for Luv N’ Care conceded that the claim was not patentable if denied the benefit of the filing date.

Second, Luv N’ Care submitted a motion to amend the patent. As reiterated by the PTAB, a motion to amend the patent must be responsive to a ground of unpatentability at issue in the trial, and it may not enlarge the scope of the claims, or introduce new matter. The patent owner bears the burden to establish that it is entitled to the relief requested by its motion to amend.

The amendment proposed by Luv N’ Care is shown in part below for Figure 3:



The PTAB stated that the “spout tip (left of center in each drawing above) is egg-shaped in the issued claim, whereas it is racetrack-shaped in the proposed amended claim. Additionally, the spout tip of the issued claim includes three concentric rings, whereas that of the proposed amended claim includes only two concentric rings.”

In its written decision, the PTAB stated that Luv N’ Care effectively argued that the proposed amended claim “is not broader than the issued claim because to ‘an ordinary observer,’ the designs are ‘substantially the same.’” However, the PTAB stated that it was not “aware of any authority that has applied the ‘ordinary observer’ test … to compare the scope of two claims.” The PTAB further noted that “the proposed amended claim is broader than the issued claim because it is broader with respect to racetrack-shaped spout tips and raised rim vents, even though it may be narrower with respect to egg-shaped spout tips and vents without raised rims.”

The PTAB held that the Petitioners had “shown by a preponderance of evidence that the sole claim of the ‘465 patent is unpatentable, and [Luv N’ Care] has not met its burden of proof on the motion to amend.”

Design Patents, PGR, and Functionality – the USPTO’s Sattler Decision

July 9, 2020
Design patents cover the ornamental design for articles of manufacture. Almost by definition, an article of manufacture is designed to perform a useful function. But if the design of an article of manufacture is dictated by its function, especially if there are no alternative designs available that perform the same function, the design patent may be invalid as lacking ornamentality under 35 USC § 171. As an aside, opinions and discussions use the terms “functionality” and “lacking ornamentality” interchangeably when discussing the 35 USC § 171 requirement for design patents. The U.S. Patent and Trademark Office (Patent Office) recently designated as Informative a decision instituting a post-grant review (PGR) proceeding on the issue of design patent functionality in Sattler Tech. Corp. v. Humancentric Ventures, LLC, PGR2019-00030, paper no. 9 (“Decision”).
