## 2. Patent Overview
- Title: Beverage System for Making a Beverage
- Brief Description: The [’430](https://ai-lab.exparte.com/case/ptab/IPR2023-00485/doc/1001) patent discloses a single-serve beverage system that uses an "identifier," such as a barcode, on a portion capsule to allow a brewing machine to determine if the capsule is suitable for use. The system is configured to control brewing parameters or prevent operation based on the identified code.

## 3. Grounds for Unpatentability

#### Ground 1: Obviousness over Yoakim, Jarisch, Rossi, and Castellani - Claims 1-10 are obvious over Yoakim in view of Jarisch, Rossi, and Castellani.
  - **Prior Art Relied Upon:** [Yoakim](https://ai-lab.exparte.com/case/ptab/IPR2023-00485/doc/1004) (Application # 2010/0239734), [Jarisch](https://ai-lab.exparte.com/case/ptab/IPR2023-00485/doc/1005) (Application # 2013/0064937), [Rossi](https://ai-lab.exparte.com/case/ptab/IPR2023-00485/doc/1041) (WO 2010/099806), and [Castellani](https://ai-lab.exparte.com/case/ptab/IPR2023-00485/doc/1009) (Application # 2008/0105131).
  - **Core Argument for this Ground:**
    - **Prior Art Mapping:** Petitioner argued that the combination of references teaches all limitations of the challenged claims. Yoakim taught the foundational centrifugal brewing system, including a capsule with a flange, a pump controlled by a barcode reader, and a seal in the brewing chamber. Jarisch taught the specific placement of an optical code on the bottom side of the capsule flange to improve readability by shielding it from coffee grounds and liquid. Rossi taught the logic of using a barcode reader to determine if a capsule belongs to an authorized group and controlling the pump to operate "only if" the capsule is recognized as appropriate, preventing the use of incorrect or unsafe capsules. Finally, Castellani taught a well-known mechanical solution for ejecting used capsules, disclosing holding arms (forks) to lift a capsule and a dropping box to collect it.
    - **Motivation to Combine:** Petitioner asserted that a person of ordinary skill in the art (POSITA) would combine these analogous references to achieve predictable results. A POSITA would modify Yoakim's system with Jarisch's barcode placement to improve the known problem of barcode readability. A POSITA would integrate Rossi’s safety and validation logic to prevent machine malfunction and ensure proper brewing, a recognized goal in the field. Adding Castellani's ejection mechanism was presented as a simple, known solution to the common problem of removing hot, wet capsules, which would ease the use of the combined Yoakim/Jarisch/Rossi system.
    - **Expectation of Success:** Petitioner contended a POSITA would have a high expectation of success. Yoakim's and Jarisch's systems are highly similar and share a common applicant. Rossi's control logic uses the same standard barcode technology found in Yoakim and Jarisch. Castellani’s mechanical ejection system is structurally compatible with the top-loading brewing head design taught by Yoakim, making its integration straightforward.

## 4. Key Claim Construction Positions
- For the purpose of the petition, Petitioner adopted the Patent Owner's apparent interpretations from related district court litigation. This was done to demonstrate that the claims are unpatentable even under the Patent Owner's proposed constructions.
- Key adopted interpretations included construing "a mandrel" as the needles that pierce the capsule's cover to allow liquid to exit, and "holding arms" as the fork elements that engage and lift the capsule for ejection. The petition argued that these features were explicitly taught by Yoakim and Castellani, respectively.

## 5. Key Technical Contentions (Beyond Claim Construction)
- A central contention was that the ’430 patent is not entitled to claim priority to its 2010 foreign applications. Petitioner argued that these earlier applications fail to provide adequate written description support for the specific combination of features recited in the challenged claims, such as a barcode on the bottom of the flange combined with an annularly convex capsule and specific brewing machine elements.
- This argument is critical because if the priority claim fails, the Jarisch reference (filed 2011) becomes undisputed prior art, which is essential to the Petitioner's primary obviousness ground.

## 6. Arguments Regarding Discretionary Denial
- Petitioner argued extensively that discretionary denial under both §325(d) and §314(a) (Fintiv) would be inappropriate.
- **§325(d) (Same or Substantially Same Art/Arguments):** Petitioner asserted that although Jarisch and Rossi were cited in a voluminous Information Disclosure Statement (IDS) during prosecution, the Examiner never substantively considered them or used them in a rejection. The petition argued the Examiner materially erred by overlooking their specific teachings, which were "buried" among nearly 700 references, and that the current petition’s detailed mapping and expert declaration present the art in a new light.
- **§314(a) (Fintiv Factors):** Petitioner argued against denial based on co-pending district court litigation because that case is stayed pending a Federal Circuit appeal on a related matter. Petitioner noted that no trial date has been set and no significant events like Markman hearings have occurred, meaning an IPR would resolve patentability far more efficiently than the stayed litigation.

## 7. Relief Requested
- Petitioner requests institution of an inter partes review and cancellation of claims 1-10 of the ’430 patent as unpatentable under 35 U.S.C. §103.
