Yanbin Yu, Zhongxuan Zhang v. Apple Inc., Fed. Cir. 2020-1760Yanbin Yu, Zhongxuan Zhang v. Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., Fed. Cir. 2020-1803
Decided on June 11, 2021
Before Newman, Prost, and Taranto (Opinion by Prost, Dissenting opinion by Newman)
Summary
Yu had ’289 patent which is titled “Digital Cameras Using Multiple Sensors with Multiple Lenses” and sued Apple and Samsung at District Court for infringement. The District Court found that the ’289 patent is directed towards an abstract idea and does not include an inventive concept. The District Court held the patent was invalid under §101 and granted the defendant’s motion to dismiss. Yu appealed to the CAFC. The majority panel affirmed the District Court’s decision. However, Judge Newman dissented and wrote that the disputed patent is directed towards a mechanical and electronic device and not an abstract idea. The Judge also pointed out that neither the majority panel nor the District Court decided patentability under §102 or 103.
Details
Background
According to Yu, early digital camera technologies were starting to flourish in the 1990s. However, before the ’289 patent, “the technological limitations of then-existing image sensors—used as the capture mechanism—caused digital cameras to produce lower quality images compared with those produced by traditional film cameras.” The’289 patent was applied in 1999 and issued in 2003. Yu believed that “the ’289 patent solved the technological problems associated with prior digital cameras by providing an improved digital camera having multiple image sensors and multiple lenses.[1]” Yu also explained that “all dual-lens cameras on the market today use the techniques claimed in the ’289 Patent[2]” and therefore, sued Apple and Samsung (“the Defendants”) for infringement of claims 1, 2, and 4 of the ’289 patent in October 2018 (before the ’289 patent expires in 2019). In response, the Defendants filed a Rule 12(b)(6) motion to dismiss, asserting that the claims are directed towards an abstract idea under §101.
Claim 1 of the ’289 patent
1. An improved digital camera comprising:
a first and a second image sensor closely positioned with respect to a common plane, said second image sensor sensitive to a full region of visible color spectrum;
two lenses, each being mounted in front of one of said two image sensors;
said first image sensor producing a first image and said second image sensor producing a second image;
an analog-to-digital converting circuitry coupled to said first and said second image sensor and digitizing said first and said second intensity images to produce correspondingly a first digital image and a second digital image;
an image memory, coupled to said analog-to-digital converting circuitry, for storing said first digital image and said second digital image; and
a digital image processor, coupled to said image memory and receiving said first digital image and said second digital image, producing a resultant digital image from said first digital image enhanced with said second digital image.
The District Court held that the ’289 patent was directed to “the abstract idea of taking two pictures and using those pictures to enhance each other in some way” and “the asserted claims lack an inventive concept, noting “the complete absence of any facts showing that the claimed elements were not well-known, routine, and conventional.” Therefore, the District Court concluded that the ’289 patent was directed to an ineligible subject matter and entered judgment for Defendants. Yu appealed to the CAFC.
Majority Opinion
At the CAFC, as we have seen in the various other §101 precedents, the panel applied the two-step Mayo/Alice framework.
Step 1: “Whether a patent claim is directed to an unpatentable law of nature, natural phenomenon, or abstract idea. Alice, 573 U.S. at 217.”
Step 2: If Step 1 is Yes, “Whether the claim nonetheless includes an “inventive concept” sufficient to “‘transform the nature of the claim’ into a patent-eligible application. Id.”
(If Step 2’s answer is No, the invention is not a patent-eligible subject matter.)
In the majority opinion filed by Judge Prost, as to Step 1, the court applied the approach to the Step 1 inquiry “by asking what the patent asserts to be the focus of the claimed advance over the prior art” and concluded that “claim 1 is “directed to a result or effect that itself is the abstract idea and merely invoke[s] generic processes and machinery” rather than “a specific means or method that improves the relevant technology.” The majority opinion also mentioned that “Yu does not dispute that, as the district court observed, the idea and practice of using multiple pictures to enhance each other has been known by photographers for over a century.” The majority opinion also noted that although, “Yu’s claimed invention is couched as an improved machine (an “improved digital camera”), … “whether a device is “a tangible system (in § 101 terms, a ‘machine’)” is not dispositive”. Thus, the majority panel concluded that “the focus of claim 1 is the abstract idea.”
As to Step 2, the majority opinion concludes that claim 1 does not include an inventive concept sufficient to transform the claimed abstract idea into a patent-eligible invention because “claim 1 is recited at a high level of generality and merely invokes well-understood, routine, conventional components to apply the abstract idea” discussed in Step 1. Yu raised the prosecution history to prove that “the ’289 patent were allowed over multiple prior art references.” Also, Yu argued that the claimed limitations are “unconventional” because “the claimed “hardware configuration is vital to performing the claimed image enhancement.” However, the court was not convinced with this argument and conclude that “the claimedhardware configuration itself is not an advance and does not itself produce the asserted advance of enhancement of one image by another, which, as explained, is an abstract idea.”
Thus, the majority of the court concluded that the ‘’289 patent is not patent-eligible subject matter under §101. Therefore, the court hold for the Defendants.
Dissenting Opinion
In the dissenting opinion, Judge Newman said that “this camera is a mechanical and electronic device of defined structure and mechanism; it is not an “abstract idea” and “a statement of purpose or advantage does not convert a device into an abstract idea.”
The judge explained that “claim 1 is not for the general idea of enhancing camera image”, but “for a digital camera having a designated structure and mechanism that perform specified functions.” The Judge further mentioned, “the ‘abstract idea’ concept with respect to patent-eligibility is founded in the distinction between general principle and specific application.” The Judge quoted Diamond v. Chakrabarty and emphasized that “Congress intended statutory subject matter to ‘include anything under the sun that is made by man.’”
Judge Newman noted that “the ’289 patent may or may not ultimately satisfy all the substantive requirements of patentability”, and noted that neither the majority opinion and the district court discussed §102 and §103.
Takeaway
- After 7 years from Alice, we are still witnessing the profound impact that Alice has on §101 jurisprudence, and waiting for further judicial, legislative, and/or administrative clarity.
- In a previous §101 decision in American Axel (previously reported by John P. Kong), the dissenting opinion by Judges Chen and Wallach criticized that §101 swallowed §112. Now, Judge Newman criticized that §101 swallowed §102 and §103. The dire warning by the Supreme Court about §101 swallowing all of patent law seems to have come full circle.
- Judge Newman’s criticism of §101 swallowing §102 and §103 can be an added argument for appeal for another case and may help get these issues before the Supreme Court.
- John P. Kong said that The approach for determining the Step 1 inquiry, i.e., “by asking what the patent asserts to be the focus of the claimed advance over the prior art” is the source of much of the court’s criticisms. This approach was never vetted, and it conflates §101 with §102 and §103 issues. First, this “focus” is just another name for deriving the “point of novelty,” “gist,” “heart,” or “thrust” of the invention, which had previously been discredited by Supreme Court and Federal Circuit decisions relating to §102 and §103 issues. The problem with tests such as these is that it subtracts out various “conventional” features of the claimed invention (like what is done for the “claimed advance over the prior art”), and thus violates the Supreme Court requirement to consider the claim “as a whole.” If the point of novelty, gist, or heart of the invention contravenes the requirement to consider the claim “as a whole” in the §102 and §103 contexts, then it should likewise contravene the same Supreme Court requirement to consider the claim “as a whole” in the §101 context (as noted in John P. Kong’ “Today’s Problems with §101 and the Latest Federal Circuit Spin in American Axle v. Neapco” powerpoint, Dec. 2020). Judge Newman’s dissent echoes the same.
- John P. Kong also said that Enfish moved up into Step 1 the “improvement in technology” comment in Alice regarding the inventive concept consideration under Step 2 because some computer technology isn’t inherently abstract and thus should not be automatically subject to Alice’s Step 2 and its inventive-concept test. Enfish only had a passing reference to “inquiring into the focus of the claimed advance over the prior art” citing Genetic Techs v. Merial (Fed. Cir. 2016), as support for considering the “improvement in technology” in Alice Step 1. Herein lies the problem. The “improvement in technology” concept pertains to whether the claims are directed to a practical application, instead of an abstract idea. The “claimed advance over prior art” is not a substitute for, and not the same as, determining whether there is a practical application reflected in an improvement in technology. Stated differently, there can still be a practical application (and therefore not an abstract idea) even without checking the prior art and subtracting out “conventional” elements from the claim to discern a “claimed advance over the prior art.” While a positive answer to the “claimed advance over the prior art” would satisfy the “improvement in technology” point as being a practical application justifying eligibility, a negative answer to the “claimed advance over the prior art” does not diminish the claim being directed to a practical application (such as for an electric vehicle charging system, a garage door opener, a manufacturing method for a car’s driveshaft, or for a camera). But, in Electric Power Group v Alstom (Fed. Cir. 2016), the Fed. Cir. considered whether the “advance” is an abstract idea using a computer as a tool or a technological improvement in the computer or computer functionality (in an “improvement in technology” inquiry). And then, in Affinity Labs of Texas LLC v. DirecTV LLC, the Fed Cir cemented the “claimed advance” spin into Step 1, subtracting out “general components such as a cellular telephone, a graphical user interface, and a downloadable application” to arrive at a purely functional remainder that constituted an abstract idea of out-of-region delivery of broadcast content, without offering any technological means of effecting that concept (the 1-2 knockout of: subtract generic elements, and no “how-to” for the remainder). This laid the groundwork for §101 swallowing §§112, 102 and 103.
