Unfair and Unjust
During the trial, Huawei submitted a circuit where ROHM components were not listed, the collegiate panel of the Shanghai Intellectual Property Court was fully aware that Honor 3Outdoor had used ROHM infrared transceivers, they compared it with the patented circuit of ZazaRemote that included ROHM components. Then, they determined non-infringement because the infrared transceivers were not found in Huawei circuit!

"Judgment (2024) Hu 73 Min Chu No. 2333" "Transcript of Online Court Hearing"The main points are as follows:
Huawei submitted a notarized certificate labeled "Circuit Diagram for Actual Use of Honor 3 Mobile Phone". ZazaRemote pointed out that the content of the notarized certificate was not the actual circuit diagram in use. ZazaRemote submitted a written application to the collegiate panel, requesting that Huawei be investigated for the crime of falsifying evidence and handed over to the public security authorities in accordance with the law. Therefore, there is a court record dated August 11, 2025:
1. During the trial, Huawei admitted that the comparison circuit submitted by Huaweiwei lacked the ROHM infrared circuit
In the "Transcription of Online Court Hearing", on the third line from the bottom on page 13, Huawei stated that "the defendant did not include the ROHM infrared head and its circuit in the infrared circuit document submitted to the court". Huawei admitted that there was a ROHM infrared head, but it was not included.
2. During the trial, Huawei admitted that the compared circuit was from Huawei's R&D process documentation and was not the final circuit
In the "Transcription of Online Court Hearing", on page 14, lines 2-4, Huawei states, "U5702... is a chip from NXP... This circuit diagram includes two schemes." On page 19, lines 4-6, Huawei states, "It's two parallel schemes, which is the upper right corner... It's abbreviated as GPIO." The circuit submitted by Huawei is a review material for the remote control scheme, listing the differences in the schemes for review, excluding the common parts.
3. During the trial, Huawei admitted that the Honor 3 uses ROHM infrared sensors
In the "Transcription of Online Court Hearing", on page 23, lines 9-13, Huawei stated, "Actually... we adopted the infrared emitter head from ROHM... This was originally Huawei's plan, because when Huawei was making this mobile phone... we chose ROHM's product." Huawei has admitted in court that the Honor 3 uses ROHM's infrared emitter head.
The patent has a total of five features, and the judgment document on page 22 confirms that Huawei's circuit possesses four of these features: 1, 3, 4, and 5. In line 8 of page 22 of the judgment document, it further compares and states, "None of the aforementioned chips are infrared transceivers... Therefore, the circuit diagrams provided by the three defendants do not possess technical features that are identical or equivalent to features 1-2 in claim 1 of the patent in question." To put it bluntly: the judgment document states that the ROHM infrared head is not found in Huawei's circuit, and feature 2 does not exist, so there is no infringement. How outrageous! ZazaRemote appeals!

The circuit patented by Huawei is consistent (equivalent) to the ROHM head Rx pin circuit patented by ZazaRemote
After ZazaRemote inadvertently discovered a similar patent to Huawei's, they disassembled and analyzed the Honor 3Outdoor phone and found that its circuit was consistent with ZazaRemote's. ZazaRemote produced disassembly mapping and comparison evidence to sue and submit another unopened Honor 3Outdoor phone to Shanghai Intellectual Property Court
"ZazaRemote Disassembly Mapping Report and Comparison Details"From 2013 to 2016, the disassembly photos provided by third parties such as Zhongguancun Online were completely consistent with those of ZazaRemote
"The disassembly photos of Honor 3Outdoor taken by multiple independent third parties are consistent in detail with the disassembly photos taken by ZazaRemote"During the first court hearing, Huawei submitted a notarized certificate labeled "Circuit Diagram of the Honor 3 Smartphone for Proof Purposes". Huawei claimed that the circuit was confidential (as the smartphone has been sold and the public can freely disassemble it, the circuit has already been made public). Only the table of contents below was provided to ZazaRemote, allowing them to view the content in court but not to take photos or make notes. Therefore, ZazaRemote is unable to provide a download of this material.
After examining the circuit presented by Huawei, ZazaRemote found that the ROHM infrared transceiver chip used in the Honor 3 Outdoor was not present on the circuit. ZazaRemote believes that Huawei has submitted incomplete evidence, as patent comparison follows the principle of full feature coverage (equivalence). Submitting an incomplete circuit will inevitably lead to errors in infringement comparison. Therefore, ZazaRemote submitted an "Application for Requesting the Court to Determine that the Defendant's Concealment of Key Circuit Evidence Constitutes Obstruction of Evidence in a Patent Infringement Dispute", requesting the court to hold Huawei responsible for perjury
"Application for Requesting the Determination that the Defendant's Concealment of Key Circuit Evidence Constitutes Obstruction of Evidence in a Patent Infringement Dispute"During the second court session, ZazaRemote persistently focused on the issue, and Huawei admitted that the ROHM infrared head used in the Honor 3Outdoor was indeed not included in the circuit presented as evidence
"Transcript of Online Court Hearing"Huawei claimed that ZazaRemote may have modified the Honor 3 Outdoor and then conducted further mapping. The collegiate panel of the Shanghai Intellectual Property Court adopted Huawei's viewpoint. Ignoring the content of the trial, the collegiate panel conducted a comparison based on the "Circuit Diagram of the Honor 3 Mobile Phone in Actual Use" submitted by Huawei. In line 8 of page 22 of the judgment, it was stated that "none of the aforementioned chips are infrared transceivers... Therefore, the circuit diagrams provided by the three defendants do not possess technical features identical or equivalent to features 1-2 in claim 1 of the patent involved", and the lawsuit brought by ZazaRemote was dismissed.

"People first" is the core guarantee for the successful achievement of the 15th Five-Year Plan. The collective interests of the people are paramount, and the basic rights and interests of individual people are of utmost importance. Without the legal system, there will be no ultimate victory in national rejuvenation.
