Method Claim with Instruction Limitation Not Obvious
Note:
A method claim including an instruction limitation does not meet the obviousness requirement if it informs about an inherent property of the known method without changing its functional relationship.

The court has extended the rationale in the printed matter cases, in which, for example, written instructions are added to a known product, to method claims in which "an instruction limitation" (i.e., a limitation “informing” someone about the existence of an inherent property of that method) is added to a method known in the art. King Pharmaceuticals, Inc. v. Eon Labs, Inc., 616 F.3d 1267, 1279, 95 USPQ2d 1833, 1842 (2010). Similar to the inquiry for products with printed matter thereon, for such method cases the relevant inquiry is whether a new and nonobvious functional relationship with the known method exists. In King Pharma, the court found that the relevant determination is whether the "instruction limitation" has a "new and unobvious functional relationship" with the known method of administering the drug with food. Id. The court held that the relationship was non-functional because "[i]nforming a patient about the benefits of a drug in no way transforms the process of taking the drug with food." Id. That is, the actual method of taking a drug with food is the same regardless of whether the patient is informed of the benefits. Id. “In other words, the ‘informing’ limitation ‘in no way depends on the method, and the method does not depend on the ‘informing’ limitation.’" Id. (citing In re Ngai, 367 F.3d 1336, 1339 (Fed. Cir. 2004)); see also In re Kao, 639 F.3d 1057, 1072-73, 98 USPQ2d 1799, 1811-12 (Fed. Cir. 2011).

Instruction Limitation Must Not Transform Known Method
Note:
The court holds that an instruction limitation in a method claim does not create a new and nonobvious functional relationship with the known method if it merely informs about inherent properties without altering the method itself.

The court has extended the rationale in the printed matter cases, in which, for example, written instructions are added to a known product, to method claims in which "an instruction limitation" (i.e., a limitation “informing” someone about the existence of an inherent property of that method) is added to a method known in the art.

Instruction Limitation Must Have New and Nonobvious Functional Relationship
Note:
For method claims with an 'instruction' limitation, the court requires that this limitation must have a new and nonobvious functional relationship with the known method.

The court has extended the rationale in the printed matter cases, in which, for example, written instructions are added to a known product, to method claims in which "an instruction limitation" (i.e., a limitation “informing” someone about the existence of an inherent property of that method) is added to a method known in the art.

Non-Functional Instruction Limitation for Drug Administration
Note:

Instruction Limitation Non-functional for Drug Administration
Note:
The court holds that informing patients about drug benefits does not change the method of administering drugs with food, making such an instruction limitation non-functional and unobvious.

The court has extended the rationale in the printed matter cases, in which, for example, written instructions are added to a known product, to method claims in which "an instruction limitation" (i.e., a limitation “informing” someone about the existence of an inherent property of that method) is added to a method known in the art.

Informing Limitation Is Independent of Method

Establishing Prima Facie Case for Identical Products
Note:
If the claimed and prior art products are identical or substantially identical, a prima facie case of anticipation or obviousness is established. The burden shifts to the applicant to show otherwise.

Where the claimed and prior art products are identical or substantially identical in structure or composition, or are produced by identical or substantially identical processes, a prima facie case of either anticipation or obviousness has been established. In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977). “When the PTO shows a sound basis for believing that the products of the applicant and the prior art are the same, the applicant has the burden of showing that they are not.” In re Spada, 911 F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990). Therefore, the prima facie case can be rebutted by evidence showing that the prior art products do not necessarily possess the characteristics of the claimed product. In re Best, 562 F.2d at 1255, 195 USPQ at 433. See also Titanium Metals Corp. v. Banner, 778 F.2d 775, 227 USPQ 773 (Fed. Cir. 1985) (Claims were directed to a titanium alloy containing 0.2-0.4% Mo and 0.6-0.9% Ni having corrosion resistance. A Russian article disclosed a titanium alloy containing 0.25% Mo and 0.75% Ni but was silent as to corrosion resistance. The Federal Circuit held that the claim was anticipated because the percentages of Mo and Ni were squarely within the claimed ranges. The court went on to say that it was immaterial what properties the alloys had or who discovered the properties because the composition is the same and thus must necessarily exhibit the properties.).

Establishes a prima facie case of anticipation when the prior art and claimed product have identical compositions, requiring evidence to show otherwise.

The claim must describe a parachute with three circumferential panels separated by tie lines, where the critical velocity of each larger panel is less than the previous one to ensure sequential opening.

See also In re Ludtke, 441 F.2d 660, 169 USPQ 563 (CCPA 1971) (Claim 1 was directed to a parachute canopy having concentric circumferential panels radially separated from each other by radially extending tie lines. The panels were separated “such that the critical velocity of each successively larger panel will be less than the critical velocity of the previous panel, whereby said parachute will sequentially open and thus gradually decelerate.” The court found that the claim was anticipated by Menget. Menget taught a parachute having three circumferential panels separated by tie lines. The court upheld the rejection finding that applicant had failed to show that Menget did not possess the functional characteristics of the claims.); Northam Warren Corp. v. D. F. Newfield Co., 7 F.Supp. 773, 22 USPQ 313 (E.D.N.Y. 1934) (A patent to a pencil for cleaning fingernails was held invalid because a pencil of the same structure for writing was found in the prior art.).

Claim Must Not Be Anticipated By Prior Art With Same Functional Characteristics
Note:
A claim is invalid if a prior art reference possesses the same functional characteristics as claimed, even if the structure differs.

Identical Chemical Products Cannot Have Mutually Exclusive Properties
Note:
If a prior art product has the same chemical composition, it must also have the claimed properties.

“Products of identical chemical composition can not have mutually exclusive properties.” In re Spada, 911 F.2d 705, 709, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990). A chemical composition and its properties are inseparable. Therefore, if the prior art teaches the identical chemical structure, the properties applicant discloses and/or claims are necessarily present. Id. (Applicant argued that the claimed composition was a pressure sensitive adhesive containing a tacky polymer while the product of the reference was hard and abrasion resistant. “The Board correctly found that the virtual identity of monomers and procedures sufficed to support a prima facie case of unpatentability of Spada’s polymer latexes for lack of novelty.”).

Printed Matter Not Distinguishing Without Functional Relationship
Note:
If the only difference between a prior art product and a claimed product is printed matter not related to functionality, it does not distinguish the claim from the prior art.

Where the only difference between a prior art product and a claimed product is printed matter that is not functionally related to the product, the content of the printed matter will not distinguish the claimed product from the prior art.
