Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Amendment
2. In an amendment dated, September 01, 2026, claims 1 and 19 are amended. Currently claims 1-20 are pending.
Response to Arguments
Applicant's arguments filed September 01, 2026, have been fully considered but they are not persuasive.
In the remarks filed on September 01, 2026, applicant argues prior art of record fails to disclose newly added claim limitation of independent claim 1 as filed wherein "a first gate electrode configured to receive a scan signal, and a second gate electrode coupled to the DC voltage”. The Examiner does not identify where Woo discloses that the body electrode is "a second gate electrode coupled to the DC voltage." Because Woo does not disclose each element arranged as recited in claim 1(added). And claim limitation of independent claim 19 as filed wherein "a first gate electrode configured to receive a scan signal, and a second gate electrode coupled to the DC voltage." The Examiner relies on Lee's switching transistor T2, which the Examiner identifies as having a gate electrode connected to a first scan line and a body electrode connected to a driving voltage line. (Office Action, p. 4.) The Examiner does not identify where Lee discloses that the body electrode is "a second gate electrode coupled to the DC voltage." The office respectfully disagrees. Independent claim(s) recites the connection of first gate electrode and second gate electrode of switching thin film transistor. Thus, as shown below prior art of recode clearly discloses the connection of first and second gate electrode of switching thin film transistor as claimed. Applicant argues limitations of independent claims 1 and 19 that are not claimed. In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., body electrode) are not recited in the rejected claim(s) 1 and 19. Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Furthermore, as to the connection of components within a circuit. Applicant recites one component connected to another component (e.g. back gate electrode of TFT to source electrode). The claim limitation does not recite a direct connection of circuit components. Thus, given the claim limitation broadest reasonable interpretation, it is clear that components of (pixel) circuit are connected to each other within said circuit; therefore, it is clearly shown within prior art of record that each components (i.e. electrodes) of said circuit would be electrically connected to each other within said circuit.

Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Woo et al (PG PUB NO 2025/0384834) in view of Miyake (PG Pub No 2013/0063413).
As in claim 2, Woo et al discloses the circuit (Fig 5) of claim 1, wherein: a drain electrode of the switching TFT is coupled to a data signal line (DLj) [(Fig 5 item TR2) discloses the connection of drain electrode and data line(DLj)] ; and a source electrode of the switching TFT is coupled to a node (N3, N1) that is further coupled to a top gate electrode of the driving TFT (TR1) and the storage capacitor (Cstg) [(Fig 5) discloses the connection]; a source electrode of the driving TFT (TR1) is coupled to the anode of the OLED (LD) (Fig 5) discloses the connection of switching TFT; but fails to disclose a back gate electrode of the driving TFT is coupled to the source electrode of the driving TFT. However, Miyake (Fig 4) discloses the back gate electrode of the driving TFT (15) is coupled to the source electrode of the driving TFT (15).

However, Shirasaki et al (Fig 2) discloses the back gate electrode of the driving TFT (Tr12) is coupled to the source electrode of the switching TFT(Tr11). Therefore, it would have been obvious to an ordinary skill person in the art at the time of the filing to modify Woo et al with the teaching of Shirasaki et al pixel drive circuit for an alternat method of connecting drive TFT and switching TFT within pixel circuit to yield same predictable outcome.
Claim(s) 4-5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Woo et al (PG PUB NO 2025/0384834) in view of Yim et al (PG Pub NO 2024/0194152).
