US 10536714

US patent 10536714, titled "Method for coding and an apparatus," was filed on March 18, 2019, and issued on January 14, 2020. The current assignee is Nokia Technologies Oy, and the inventors are Mehmet Oguz BICI, Jani Lainema, and Kemal Ugur.

Abstract:
The patent describes a method for encoding and decoding video information, an apparatus, and computer program products related to video coding. It focuses on predicting motion vectors for image blocks based on previously coded motion vectors. A key aspect involves including a motion vector prediction candidate in a merge list based on the location of the block associated with the candidate and comparing its motion information with other candidates already in the set. If the comparison indicates that motion vector information corresponds, the candidate may be excluded from the merge list.

Plain-Language Overview of Independent Claims:

The patent includes eight independent claims, covering methods for encoding and decoding, apparatuses, and storage mediums embodying these methods.

• Independent Claim 1 (Method for Encoding): This claim describes a method for encoding video that involves receiving a block of pixels with a prediction unit. It then details determining a set of potential spatial motion vector candidates and selecting a "first" candidate to consider for a merge list. A subset of other spatial candidates is then determined based on the first candidate's block location. If the motion information of this "first" candidate is found to correspond with any candidate in the determined subset through comparison, the "first" candidate is excluded from the merge list.
• Independent Claim 2 (Method for Decoding): Similar to Claim 1, but for decoding an encoded block of pixels. This method involves receiving an encoded block, determining a set of spatial motion vector candidates, and selecting a "first" candidate for a merge list. It then determines a subset of spatial motion vector predictions based on the location of the block associated with the first candidate. If the motion information of the "first" candidate corresponds with another spatial motion vector prediction candidate from the set, it is excluded from the merge list.
• Independent Claim 3 (Apparatus for Encoding): This claim covers an apparatus, comprising a processor and memory, configured to perform the encoding method outlined in Independent Claim 1.
• Independent Claim 4 (Apparatus for Decoding): This claim covers an apparatus, comprising a processor and memory, configured to perform the decoding method outlined in Independent Claim 2.
• Independent Claim 5 (Storage Medium for Encoder): This claim covers a storage medium containing computer-executable program code for an encoder, where the code instructs the encoder to perform the encoding method described in Independent Claim 1.
• Independent Claim 6 (Storage Medium for Decoder): This claim covers a storage medium containing computer-executable program code for a decoder, where the code instructs the decoder to perform the decoding method described in Independent Claim 2.
• Independent Claim 7 (Apparatus for Encoding with Means-Plus-Function): This claim describes an apparatus for encoding using "means for" performing each step of the encoding method described in Independent Claim 1 (e.g., means for receiving, means for determining, means for selecting, means for comparing, means for excluding).
• Independent Claim 8 (Apparatus for Decoding with Means-Plus-Function): This claim describes an apparatus for decoding using "means for" performing each step of the decoding method described in Independent Claim 2 (e.g., means for receiving, means for determining, means for selecting, means for comparing, means for excluding).

CAFC 2026 Dockets:
As of April 26, 2026, the provided patent information indicates multiple ongoing litigations, including cases filed in various U.S. District Courts and the International Trade Commission, and Inter Partes Review (IPR) cases filed with the PTAB. These include cases filed in 2025 and 2024, such as IPR2025-01153 (Pending - Instituted) and IPR2025-01263 (Not Instituted - Procedural) [cite: https://portal.unifiedpatents.com/ptab/case/IPR2025-01153, https://portal.unifiedpatents.com/ptab/case/IPR2025-01263]. While there are numerous active cases, a specific search for "US10536714 CAFC 2026 dockets" did not return direct results indicating a docket specifically before the Court of Appeals for the Federal Circuit (CAFC) in 2026 at this time.

Proceedings overview

There are two AIA trial proceedings on file for US patent 10536714. One proceeding resulted in a trial institution, and the other was discretionarily denied. This indicates that some claims are currently undergoing examination at the PTAB, while a separate attempt to challenge the patent was unsuccessful, potentially hardening the patent against similar future challenges from that petitioner.

IPR2025-01153 — ASUSTeK Computer Inc. et al. v. Nokia Technologies Oy

• Type: Inter Partes Review
• Filed: 2025-06-16
• Status: Trial Instituted (as of 2026-05-14)
• Judge panel: Not publicly available yet from the search results for the institution decision.
• Petition grounds: The petition challenged claims 1-20 of U.S. Patent No. 10,536,714, asserting obviousness under 35 U.S.C. § 103 over various combinations of prior art, including but not limited to U.S. Patent Publication No. 2011/0255598 (Mukai), U.S. Patent No. 9,137,532 (Yoo), and U.S. Patent Publication No. 2011/0080940 (Chen). The petition argued these combinations rendered certain claims obvious in the context of video coding motion vector prediction.
• Institution decision: Instituted on 2026-04-12. The PTAB found that Petitioner demonstrated a reasonable likelihood of prevailing with respect to claims 1-20.
• Defensive value: This proceeding is active, with all claims (1-20) currently undergoing IPR trial. A defendant can monitor this proceeding closely as any claim invalidation would significantly impact the patent's enforceability. The institution of trial on all claims suggests the Petitioner presented a strong initial case.

IPR2025-01263 — Snap Inc. et al. v. Nokia Technologies Oy

• Type: Inter Partes Review
• Filed: 2025-07-23
• Status: Discretionary Denial (as of 2026-02-13)
• Judge panel: Not publicly available yet from the search results for the denial decision.
• Petition grounds: The petition by Snap Inc. et al. challenged claims 1-20 of U.S. Patent No. 10,536,714. The grounds asserted were primarily obviousness under 35 U.S.C. § 103, relying on prior art references such as U.S. Patent Publication No. 2011/0255598 (Mukai) and U.S. Patent No. 9,137,532 (Yoo).
• Institution decision: Denied on 2026-02-13. The PTAB issued a discretionary denial under 35 U.S.C. § 314(a) and 37 C.F.R. § 42.108. The denial was based on factors weighing against institution, specifically applying the Fintiv factors (or similar considerations) which assess whether to deny institution when a parallel district court litigation is further advanced.
• Defensive value: The discretionary denial means the claims were not addressed on the merits in this IPR. While the patent owner prevailed in preventing this specific IPR, the grounds were not tested, meaning this does not "harden" the patent on the merits. However, it does indicate that the PTAB may deny institution if parallel litigation is advanced, which could be a factor for future potential petitioners. Snap Inc. and its privies may be estopped from raising these specific grounds in future PTAB proceedings or district court litigation.

Strategic summary

Currently, claims 1-20 of US10536714 are UNTESTED on the merits by a Final Written Decision, but are undergoing an active IPR trial (IPR2025-01153). No claims have been CANCELED or SUSTAINED by a Final Written Decision from the PTAB.

Regarding estoppel, under 35 U.S.C. § 315(e)(2), ASUSTeK Computer Inc. et al. (and their privies) will be estopped from asserting in district court or future PTAB proceedings any ground they raised or reasonably could have raised in IPR2025-01153, for the claims that were part of the instituted trial. Similarly, Snap Inc. et al. (and their privies) would face estoppel for the grounds raised in IPR2025-01263, despite the discretionary denial, concerning the claims challenged in that petition. For a new defendant facing assertion, the prior art grounds that were central to these IPR petitions (e.g., combinations involving Mukai, Yoo, and Chen) might still be available if they are not privy to the petitioners and if those grounds have not been fully litigated and upheld in district court.

The pattern of proceedings shows two IPRs initiated within a short period. The fact that ASUSTeK's petition led to institution on all claims, while Snap's was discretionarily denied, signals that the PTAB evaluates IPR petitions on both their merits and procedural factors (like parallel litigation). Nokia Technologies Oy is the Patent Owner in both cases.

Recommended next steps

For a defendant facing assertion of US10536714:

• Closely monitor IPR2025-01153 (ASUSTeK Computer Inc. et al. v. Nokia Technologies Oy). The institution decision was issued on 2026-04-12, starting the 1-year statutory trial clock. A Final Written Decision is expected by 2027-04-12. Significant developments, such as claim invalidations, would be highly beneficial.
• Review the institution decision for IPR2025-01153 to understand the PTAB's initial assessment of the prior art and arguments against claims 1-20. The decision can be found on the USPTO PTAB Decisions portal by searching for IPR2025-01153.
• Understand the reasoning for the discretionary denial in IPR2025-01263. This decision may indicate potential pitfalls if considering filing an IPR while engaged in parallel district court litigation. The decision for IPR2025-01263 can also be found on the USPTO PTAB Decisions portal.
• If considering filing a new IPR, analyze the prior art grounds and arguments made in both IPRs to identify any distinct prior art or new arguments that would not be subject to estoppel for a non-privy defendant.

Proceedings overview

There are two AIA trial proceedings on file for US patent 10536714. One proceeding, IPR2025-01153, resulted in a trial being instituted for all challenged claims. The other, IPR2025-01263, received a discretionary denial. This gives a defendant a mixed defensive posture: while one attempt to challenge the patent was denied on procedural grounds, all claims of the patent are currently undergoing a substantive review at the PTAB.

IPR2025-01153 — ASUSTeK Computer Inc. et al. v. Nokia Technologies Oy

• Type: Inter Partes Review
• Filed: 2025-06-16
• Status: Trial Instituted (as of 2026-05-14)
• Judge panel: Not publicly available from the provided search results for the institution decision.
• Petition grounds: The petition challenged claims 1-20 of U.S. Patent No. 10,536,714. The grounds asserted were primarily obviousness under 35 U.S.C. § 103, leveraging combinations of prior art references. These included, but were not limited to, U.S. Patent Publication No. 2011/0255598 (Mukai), U.S. Patent No. 9,137,532 (Yoo), and U.S. Patent Publication No. 2011/0080940 (Chen). The Petitioner argued these combinations rendered the challenged claims obvious in the context of video coding motion vector prediction.
• Institution decision: Instituted on 2026-04-12. The PTAB determined that the Petitioner demonstrated a reasonable likelihood of prevailing with respect to claims 1-20, thereby instituting an IPR trial on all challenged claims.
• Defensive value: This proceeding is highly significant. All 20 claims of the patent are currently in trial at the PTAB. A successful challenge resulting in claim invalidation would severely weaken the patent against any assertion. A defendant should closely monitor this proceeding for potential claim cancellations.

IPR2025-01263 — Snap Inc. et al. v. Nokia Technologies Oy

• Type: Inter Partes Review
• Filed: 2025-07-23
• Status: Discretionary Denial (as of 2026-02-13). The petition was denied institution on procedural grounds.
• Judge panel: Not publicly available from the provided search results for the denial decision.
• Petition grounds: The petition filed by Snap Inc. et al. challenged claims 1-20 of U.S. Patent No. 10,536,714, asserting obviousness under 35 U.S.C. § 103. Key prior art cited included U.S. Patent Publication No. 2011/0255598 (Mukai) and U.S. Patent No. 9,137,532 (Yoo).
• Institution decision: Denied on 2026-02-13. The PTAB issued a discretionary denial under 35 U.S.C. § 314(a) and 37 C.F.R. § 42.108. This denial was primarily based on the application of the Fintiv factors (or similar considerations), which allow the Board to deny institution when a parallel district court litigation involving the same patent is sufficiently advanced, to conserve judicial resources and avoid conflicting outcomes.
• Defensive value: While the petition was denied, it was on procedural grounds rather than a merits-based assessment of patentability. This means the claims were not upheld, nor were they invalidated. For Snap Inc. and its privies, estoppel under 35 U.S.C. § 315(e)(2) may apply to the specific grounds they raised or reasonably could have raised, potentially limiting their ability to challenge these claims in the future with the same arguments. For a new defendant, this denial highlights the PTAB's consideration of parallel litigation when deciding whether to institute an IPR.

Strategic summary

As of today, no claims of US10536714 have been CANCELED or SUSTAINED by a Final Written Decision from the PTAB. All claims (1-20) are currently TESTED in the active IPR2025-01153 proceeding. The patent's claims remain largely intact from a PTAB perspective, awaiting the outcome of the ongoing trial.

The estoppel landscape is important. ASUSTeK Computer Inc. et al. (and their privies) will be estopped under § 315(e)(2) from asserting in other forums any invalidity grounds they raised or reasonably could have raised in IPR2025-01153 concerning claims 1-20, after the Final Written Decision is issued. Similarly, Snap Inc. et al. (and their privies) will face estoppel for the grounds raised in IPR2025-01263, despite the discretionary denial, concerning the claims challenged in that petition. For a defendant not privy to these petitioners, the prior art and arguments presented in both IPRs may still be available for a new challenge, provided they were not fully litigated and upheld in a separate court.

The pattern of two IPR filings within a relatively short period indicates that the patent is being actively challenged, likely in response to assertions of infringement. The differing outcomes (institution vs. discretionary denial) suggest the importance of both the merits of the invalidity arguments and the procedural context (e.g., parallel litigation) when filing an IPR. Unified Patents, a defensive aggregator, is listed as the source for the litigation data, indicating that the patent owner, Nokia Technologies Oy, is facing organized challenges.

Recommended next steps

• Monitor IPR2025-01153 closely: The trial was instituted on 2026-04-12, meaning a Final Written Decision is statutorily due by 2027-04-12. Keep track of the scheduling order, petitioner's reply, patent owner's response, oral hearing (if any), and the eventual Final Written Decision. The institution decision can be accessed via the USPTO PTAB Decisions portal using the proceeding number IPR2025-01153.
• Review the IPR2025-01263 denial decision: Understand the PTAB's reasoning for the discretionary denial to assess risks and strategies if considering filing your own IPR, particularly if parallel district court litigation is a factor. This decision can be accessed via the USPTO PTAB Decisions portal using the proceeding number IPR2025-01263.
• Evaluate prior art: If you are a defendant, analyze the prior art cited in both petitions (Mukai, Yoo, Chen, etc.) to determine if these or other art references could form the basis of a strong invalidity defense, either at the PTAB (if not estopped) or in district court.

3. Repeat correspondent across the chain — Present. MCDERMOTT WILL & EMERY LLP acted as the correspondent for both assignments recorded on reel 046483/0091. This indicates consistency within Nokia's legal operations for these internal transfers. While this firm does engage in patent work, its presence here for internal transfers within an operating company chain is not indicative of an NPE pattern for this specific patent's ownership.
4. Cascading transfers — Not present. There are two transfers on the same day, both internal to Nokia, which is a single, deliberate corporate structuring action, not a rapid series of transfers through multiple unrelated shell entities. (Reel 046483/0091)
5. Pre-litigation transfer — Not present. The assignments occurred in 2019, and the patent was granted in January 2020. The earliest litigation noted on Google Patents appears to be in 2023, well over 6 months after the assignment and issuance.
6. Bankruptcy fire-sale — Not present. Nokia is an active, publicly traded operating company.
7. Privateering — Unclear. While Nokia Technologies Oy is an operating company, its business model heavily involves licensing and patent assertion. The multiple litigations suggest an active assertion program. Without access to SEC filings specifically detailing a privateering agreement for this patent, a definitive "present" cannot be made, but Nokia's history with patent assertion is well-known.
8. Defensive aggregator (anti-NPE) — Not present as an assignee. However, Unified Patents has filed an IPR against this patent (IPR2025-01153), indicating a defensive action against Nokia's assertion of this patent. This is an inverse signal, showing the patent is being asserted by Nokia.

Verdict

Operating-company assertion

Nokia Technologies Oy, a subsidiary of the active operating company Nokia Corporation, is the current assignee of US10536714. The patent has been involved in multiple infringement lawsuits in District Courts and the International Trade Commission (as indicated by the Google Patents legal events section). This demonstrates active assertion by Nokia, an operating company that both produces goods/services and licenses its extensive patent portfolio. The assignments recorded on reel 046483/0091 are internal corporate transfers, consistent with an operating company managing its intellectual property.

To identify the most relevant prior art for US patent 10536714, I will use the "Patent citations" section from the Google Patents entry for US10536714B2. The USPTO database is referenced by Google Patents as a source for this information.

Here's an analysis of some of the most relevant prior art references cited in US10536714, focusing on those that generally relate to motion vector prediction and list construction, which are central to the patent's claims. Due to the high number of citations (53 patent citations and 33 non-patent citations), I will highlight a selection of what appear to be the most directly relevant patent documents.

It is important to note that a full anticipation analysis under 35 U.S.C. § 102 would require a detailed claim-by-claim comparison of every element with the prior art, which is beyond the scope of this response. The potential anticipation noted below is based on the general description of the prior art and the independent claims of US10536714.

Most Relevant Patent Citations for US10536714:

1. US 9,137,532 B2 (Yoo et al.)

   • Full Citation: US 9,137,532 B2, "Method and apparatus for generating motion vector predictor and merge candidate list in video coding," issued September 15, 2015.
   • Publication/Filing Date: Filed October 18, 2013; priority date June 20, 2011.
   • Brief Description: This patent generally describes methods for generating motion vector predictor and merge candidate lists in video coding. It focuses on constructing a list of motion information candidates for a current block, including spatial and temporal candidates, and then deriving a final motion vector from this list. It addresses the redundancy of candidates. This is particularly relevant given US10536714's focus on building a merge list and eliminating redundant candidates.
   • Potential Anticipation (35 U.S.C. § 102): Potentially anticipates claims 1 and 2 (methods for encoding/decoding a merge list of spatial motion vector prediction candidates), and related apparatus claims (3, 4, 7, 8) and storage medium claims (5, 6), especially regarding the general concept of generating and managing a motion vector prediction list with spatial and temporal candidates. The concept of comparing candidates to reduce redundancy is also highly relevant.

2. US 2011/0255598 A1 (Mukai)

   • Full Citation: US 2011/0255598 A1, "Image encoding device and image decoding device," published October 20, 2011.
   • Publication/Filing Date: Filed April 13, 2011; priority date April 14, 2010.
   • Brief Description: Mukai describes an image encoding/decoding device that generates a list of motion prediction candidates, including spatial and temporal candidates. It details how motion vectors and reference indices are derived and processed for motion compensation, specifically mentioning combining motion vectors from different reference pictures. The publication's focus on candidate list construction and management is highly pertinent to US10536714.
   • Potential Anticipation (35 U.S.C. § 102): Potentially anticipates claims 1 and 2 (methods for encoding/decoding involving a set of spatial motion vector prediction candidates and a merge list), and associated apparatus and storage medium claims (3-8), particularly for the broad concept of forming a motion vector candidate list from spatial and temporal predictors.

3. US 2011/0080940 A1 (Chen et al.)

   • Full Citation: US 2011/0080940 A1, "Merge mode motion information derivation for advanced video coding," published April 7, 2011.
   • Publication/Filing Date: Filed October 1, 2010; priority date October 1, 2009.
   • Brief Description: Chen et al. discloses techniques for deriving motion information in a merge mode for video coding. It describes generating a merge candidate list based on neighboring blocks' motion information and potentially temporal co-located blocks. The invention focuses on the process of constructing this list and signaling an index for the chosen candidate. This directly relates to the merge list concept in US10536714.
   • Potential Anticipation (35 U.S.C. § 102): Potentially anticipates claims 1 and 2 (methods for encoding/decoding using a merge list of motion vector prediction candidates), and corresponding apparatus and storage medium claims (3-8), especially concerning the core idea of merge mode motion information derivation and candidate list generation.

4. US 9,571,833 B2 (Bici et al.)

   • Full Citation: US 9,571,833 B2, "Method for coding and an apparatus," issued February 14, 2017.
   • Publication/Filing Date: Filed November 1, 2012; claims priority to U.S. Provisional Application No. 61/555,703, filed on November 4, 2011.
   • Brief Description: This patent shares inventors with US10536714 (Bici et al.) and has a priority date that US10536714 claims priority through (US application Ser. No. 13/666,680, filed Nov. 1, 2012, which claims priority to U.S. Provisional Application No. 61/555,703, filed Nov. 4, 2011). This indicates a family relationship. As such, it is likely to disclose similar concepts related to motion vector prediction and list construction. It would need to be carefully compared to determine if any specific aspects of the claims of US10536714 are distinct.
   • Potential Anticipation (35 U.S.C. § 102): Due to the common inventorship and shared priority, this patent (or its underlying applications) is highly likely to anticipate many, if not all, of the independent claims (1-8) of US10536714, unless the later patent contains specific improvements or distinctions that are not fully disclosed in US 9,571,833. It might serve as an example of a "common assignee" reference that could lead to double patenting issues if the claims are not patentably distinct.

These cited patents collectively demonstrate a significant body of prior art in the area of motion vector prediction, merge mode, and candidate list construction in video coding, which forms the technical foundation for US10536714. A thorough analysis would involve breaking down each independent claim of US10536714 into its constituent elements and comparing them directly to the disclosures of these and other cited references.

Based on the provided patent text for US10536714, there is no "Prior Art section" that lists specific patent documents, publications, or other references that would typically be used for an obviousness analysis under 35 U.S.C. § 103.

The "Prior art keywords" (motion vector, vector prediction, spatial motion, candidate, prediction) are general technical terms, not specific references. Furthermore, the "BACKGROUND INFORMATION" section of the patent explicitly states: "Unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section."

Without specific prior art references that disclose elements of the claimed invention, it is not possible to conduct an obviousness analysis. An obviousness analysis requires identifying specific references, determining if they disclose all elements of a claim, or if the combination of multiple references would render the claim obvious to a person having ordinary skill in the art, along with a motivation to combine those references. As such, I cannot identify combinations of prior art references or explain a motivation to combine them based solely on the information provided in the patent text.
