IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

SECOND APPELLATE DISTRICT

DIVISION TWO

ROBERTA MARK ENGEL, B346269 (Los Angeles County Plaintiff and Appellant, Super. Ct. No. 24STCV16929)

v.

GARY ENGEL,

Defendant and Respondent.

APPEAL from an order of the Superior Court of Los Angeles County, Daniel M. Crowley, Judge. Affirmed.

Law Offices of Lawrence P. House and Lawrence P. House for Plaintiff and Appellant.

Lewitt, Hackman, Shapiro, Marshall & Harlan and Thomas M. Morrow for Defendant and Respondent. Plaintiff and appellant (appellant) Roberta Mark Engel appeals from the judgment of dismissal following defendant and respondent Gary Engel’s (respondent) successful demurrer. Appellant contends the trial court erred in concluding the statute of limitations bars her claims, finding her prior declaration showed she knew respondent had exploited his patent for income and profits. We conclude appellant’s causes of action are time- barred based on her prior declaration showing she had then known the facts constituting her claims. Thus, we affirm.

BACKGROUND The divorce Appellant and respondent were married on August 17, 1975, and divorced on December 17, 2013. During their marriage, respondent was a collector and renowned expert of Japanese baseball cards. Respondent also developed an invention in the field of orthodontics, which became the subject of a U.S. Patent, No. 5,278,756 (issued Jan. 11, 1994) (’756 patent). In February 2019, appellant brought further court proceedings against respondent, filing a request for order regarding undisclosed assets and attorney’s fees and costs. Appellant asserted she became aware in November 2018 of additional assets not disclosed and divided during the dissolution of marriage. The undisclosed assets included respondent’s Japanese baseball cards and patents. The petition raised theories of fraud and breach of fiduciary duty, asserting respondent had duties of disclosing any transaction concerning community property. Appellant submitted a declaration to support her petition, attesting to several facts regarding respondent’s allegedly

2 undisclosed businesses and patents, including respondent and Marc Lemchen’s 1985 cofounding of Dolphin Imaging Systems (Dolphin Imaging) and their creation of new technology. Before Dolphin Imaging was formed, respondent had a company called Sonrisa Systems Inc., which became Dolphin Imaging. Respondent hid his involvement in Dolphin Imaging during his marriage with appellant. While at Dolphin Imaging, respondent helped co-author domestic and international patents, 3D technologies, and software that helped in all areas of dental specialty practice. By 1995, respondent was president of Dolphin Imaging and worked to form a limited liability company for the business. In 1998, Dolphin Imaging was dissolved and assumed by Dolphin LLC. Dolphin LLC operated until 2009 when Patterson Dental acquired it as a standalone subsidiary and designated Chester Wang as subsidiary president. At that time Dolphin LLC already had its manufacturing at Patterson Dental’s facility. Wang told a private investigator hired by appellant that he offered to buy Dolphin LLC and respondent accepted. Wang claimed, however, he did not pay to acquire the company and instead agreed to reimburse respondent for money “he ‘borrowed from his mother.’” Respondent told appellant this money “never changed hands” when he left the company. After appellant discovered the sale of Dolphin LLC, she investigated how respondent could hide large sums of money and discovered various trusts and a real property disposition that had not been disclosed in the divorce proceedings. Appellant found Wang never purchased Dolphin LLC, and respondent remained a major stakeholder. Appellant averred respondent likely received substantial income from the software and patents he helped develop and from Dolphin LLC being sold to Patterson Dental for

3 approximately $42 million. Appellant’s declaration also referenced and attached a letter from her attorney to respondent’s then-attorney that discussed undisclosed assets and stressed that appellant did not waive respondent’s fiduciary obligation. Appellant’s counsel thanked respondent’s counsel in the letter for providing “the Dolphin paperwork” and asked, “Is Mr. Engel willing to put under oath that he never received a dime beyond that Asset Purchase Agreement for Dolphin, patents, etc?” Following a hearing held on appellant’s petition in April 2019, the trial court issued a stipulated findings and order dismissing appellant’s petition with prejudice. The order indicated appellant shall not request the relief set forth in her petition, and the parties were to bear their own associated attorney’s fees and costs. Each party stipulated to the dismissal. The lawsuit In July 2024, appellant filed a lawsuit against respondent asserting three causes of action for extrinsic fraud, breach of fiduciary duties, and intentional infliction of emotional distress. Appellant alleged respondent defrauded her and breached his fiduciary duties throughout their marriage by actively concealing the scope of his baseball card business, his development of the invention in orthodontics and the associated ’756 patent, and his business of purchasing and selling real estate. Respondent allegedly kept secret his involvement in and the assignments of the ’756 patent until late 2023 when appellant learned of the invention and its potentially high value. Appellant alleged she discovered the fraud in December 2023 when she learned her dentist used Patterson Dental Unit equipment. Appellant became more intrigued by this discovery

4 when she later saw an advertisement by Lemchen on the Web site LinkedIn discussing an application he and Wang created on behalf of Dolphin LLC. Appellant alleged she was jarred by the advertisement due to respondent’s representation he received no money from Wang for Dolphin LLC, which was supposedly a “gift.” Appellant realized respondent could not simply have given the company to Wang because he co-owned it with Lemchen. Respondent allegedly represented to appellant there were no businesses in which he was involved that were not disclosed during their marriage. Appellant alleged respondent represented he was not involved in Dolphin LLC or its patents. Appellant further alleged, despite respondent’s representations, he was critical to forming Dolphin Imaging and its operation and patents because he cofounded and was an officer of the company. Appellant alleged she realized respondent was part of Patterson Dental and a coholder of the patent with Lemchen. In August 2024, respondent filed a demurrer to the complaint. Before the trial court ruled on the demurrer, appellant filed an amended complaint (FAC) in October 2024. The demurrer to the FAC In November 2024, respondent filed a demurrer to the FAC. Respondent contended the statute of limitations bars all of appellant’s three causes of action. Respondent argued the one- year statute of limitations under Family Code section 2122 bars appellant’s first and second causes of action for extrinsic fraud and breach of fiduciary duties. Respondent argued the documents appellant filed in the 2019 proceeding show she knew as of February 21, 2019, the alleged facts constituting her claims for fraud and failure to comply with the applicable disclosure

5 requirements.
