Opinion

DATO, J.

*227In this writ proceeding, the People seek relief from a discovery order requiring them to produce certain materials related to DNA testing in a criminal action. With respect to the four categories of evidence at issue, three separate grounds for relief are pursued. We find each has merit. Accordingly, we grant the relief requested by the People in full.

FACTUAL AND PROCEDURAL BACKGROUND

Petitioner Florencio Jose Dominguez stands accused of conspiracy to commit murder.1 (See Pen. Code, §§ 182, subd. (a), 187.)2 For the purposes of this writ proceeding, one piece of evidence expected to be introduced at his upcoming trial is central: results from DNA testing conducted on a pair of blood-soaked gloves found near the scene of the crime.

No one disputes that DNA testing established the blood on the gloves' exterior to be that of victim. DNA on swabs from the gloves' interior, however, could not be tied to a single source. Rather, those swabs yielded a low template DNA mixture with multiple contributors. (See *74People v. Lazarus (2015) 238 Cal.App.4th 734, 784, fn. 51, 190 Cal.Rptr.3d 195 [" 'Low template' DNA testing ... refers to testing performed on 'amounts of DNA *228that are at or below the "stochastic threshold." ' "].) Given the number of contributors, the mixture was characterized as "complex." (See Phillips v. State (2015) 226 Md.App. 1, 126 A.3d 739, 741, fn. 3 ["A 'complex' DNA sample refers to a DNA sample that includes genetic material from three or more individuals"].)

The San Diego Police Department Crime Lab (the lab) tested the swabs using the STRmix program, which it purchased in 2015 from the U.S. distributor (NicheVision) of a research institute owned by the government of New Zealand (the Institute of Environmental Science and Research Limited, aka ESR). STRmix is a "probabilistic genotyping" program-i.e., one that " 'comprise[s] ... software, or software and hardware, with analytical and statistical functions that entail complex formulae and algorithms.' " (Chin et al., Forensic DNA Evidence: Science and the Law (The Rutter Group 2018) ¶ 11:7.) It produces a likelihood ratio, which is generally "expressed as follows: a match between the suspect and the evidence is (x number) of times more probable than a coincidental match." (See People v. Bullard-Daniel (N.Y.Sup.Ct. 2016) 54 Misc.3d 177, 42 N.Y.S.3d 714, 717, fn. 4.) Probabilistic genotyping has been described as " '[p]articularly useful for low-level DNA samples ... and complex mixtures' " since it " 'can reduce subjectivity in the analysis of DNA typing results.' " (Chin et al., Forensic DNA Evidence: Science and the Law, supra , ¶ 11:7.)

In February 2018, defense counsel informally requested discovery of materials related to the STRmix program from the People. (See § 1054.1.) Four categories of that request are pertinent to this writ proceeding: (1) the STRmix user manual and any related updates; (2) the STRmix software program and any related updates; (3) the STRmix program's source code; and (4) ESR's internal validation studies and related documents.

In response to the informal discovery request, the prosecutor declared that the lab could not provide (1) the user manual because "it is copyrighted by ESR"; (2) the software because it would "not work without a license," which only ESR could furnish; (3) the source code because the lab "[d]oes not have knowledge or capacity" to do so; and (4) ESR's general internal validation records, presumably because the lab did not have them. The prosecutor further declared that ESR indicated it would produce all four pursuant to its "Defense Access Policy," which required execution of a nondisclosure agreement (NDA).

The NDA, in turn, imposed certain confidentiality restrictions on "protected information" related to and including the STRmix program. Among those restrictions, the agreement required that the recipient of the information not "disclose or release Protected Information to any third party except with *229the specific prior written consent of ESR or except as expressly otherwise permitted in this Agreement." A separate section entitled "Legal Proceedings," specified:

"If Recipients or any of Recipients' Affiliates become legally compelled (by oral questions, interrogatories, requests for information or documents, subpoena, civil or criminal investigative demand, or similar process) to make any disclosure that is prohibited or otherwise constrained by this Agreement, Recipient or such Affiliate will provide ESR with prompt written notice of such legal proceeding(s) so that it may seek an appropriate protective order or other appropriate relief including, but not limited to, *75an order to have any testimony or records sealed, or waive compliance with the provisions of this Agreement. In the absence of a protective order or Recipients receiving such a waiver from ESR, Recipients or Recipients' Affiliates are permitted (with ESR's cooperation but at Recipients' expense) to disclose that portion (and only that portion) of the Protected Information that Recipients or Recipients' Affiliates are legally compelled to disclose, provided however, that Recipients and Recipients' Affiliates must use reasonable efforts to obtain reliable assurance that confidential treatment will be accorded by any person to whom any Protected Information is so disclosed."

Apparently finding the possibility of obtaining the information under the NDA unsuitable, Dominguez moved to compel the People's production of the materials related to the STRmix program. He asserted that ESR was part of the prosecution team and so the onus was on the People to obtain documents from it. He further argued that his right to a fair trial and effective cross-examination overrode any intellectual property concerns. Specifically as to the possibility of obtaining the material under the NDA, defense counsel deemed it untenable since in his view, that agreement might interfere with his use of the materials to defend his client.

In their responsive briefing, the People disputed the relevance of the requested items and ESR's purported status as part of the prosecution team. The People also represented that ESR claimed trade secret privilege over the targeted materials.

Separately, Dominguez sought the materials in question directly from ESR by way of a subpoena duces tecum.
