2. INTRODUCTION
2.1. Plaintiff [PLAINTIFF NAME] ("Plaintiff"), by and through undersigned counsel, brings this action against Defendants for personal injuries proximately caused by Defendants' failure to provide adequate warnings and instructions regarding the foreseeable risks of harm associated with [PRODUCT TYPE] (the "Product"), which Defendants designed, manufactured, marketed, distributed, and/or sold. Plaintiff alleges as follows on personal knowledge as to facts pertaining to Plaintiff and on information and belief as to all other matters.
3. PARTIES
3.1. Plaintiff [PLAINTIFF NAME] is, and at all relevant times was, an individual residing in [COUNTY] County, California.
3.2. Defendant [MANUFACTURER NAME] ("Manufacturer") is, and at all relevant times was, a corporation organized under the laws of [STATE] with its principal place of business in [CITY, STATE], engaged in the business of designing, manufacturing, testing, labeling, marketing, and selling the Product, and regularly conducting business in California and in this County.

3.4. The true names and capacities of Defendants sued as DOES 1 through 50 are unknown to Plaintiff, who therefore sues them by fictitious names pursuant to Code of Civil Procedure § 474 and will amend when ascertained.
3.5. Plaintiff is informed and believes that each Defendant was the agent, employee, alter ego, successor-in-interest, or co-participant of each other Defendant and acted within the scope of that relationship. Each Defendant is a participant in the chain of distribution of the Product within the meaning of Greenman v. Yuba Power Products, Inc., 59 Cal.2d 57 (1963), and Vandermark v. Ford Motor Co., 61 Cal.2d 256 (1964).
4. JURISDICTION AND VENUE

A. The Product
5.1. The Product at issue is [PRODUCT NAME / MODEL / DESCRIPTION; for a drug or device: drug/device name, NDC or model number, lot] (the "Product").
5.2. The Product was designed, manufactured, labeled, marketed, distributed, and/or sold by Defendants and reached Plaintiff without substantial change in the condition in which it was sold.
B. The Risk and the Inadequate or Absent Warning
5.3. The Product posed a risk of [DESCRIBE RISK / HAZARD] when used in its intended or reasonably foreseeable manner.
5.4. The risk was known or knowable in light of the scientific and medical knowledge generally accepted in the relevant scientific community at the time of manufacture and distribution, as required by Anderson v. Owens-Corning Fiberglas Corp., 53 Cal.3d 987 (1991). Defendants knew or should have known of the risk because: [pre-market testing; adverse-event/post-market surveillance; scientific literature; consumer complaints; regulatory communications; other — [____]].
5.5. Ordinary consumers would not have recognized the risk based on common knowledge.
5.6. Defendants failed to provide any warning of the risk, or the warnings and instructions actually provided were inadequate because they [failed to describe the nature/severity of the risk; failed to describe how to avoid it; were not reasonably prominent or legible; used unclear or technical language; were not updated after the risk became known — [____]].
5.7. An adequate warning should have stated, in substance: [____].
C. Plaintiff's Use and Injury
5.8. On or about [__/__/____], Plaintiff [purchased / was prescribed / used] the Product in a manner that was intended and reasonably foreseeable.

6. FIRST CAUSE OF ACTION — STRICT PRODUCTS LIABILITY: FAILURE TO WARN
(Against All Defendants)
6.1. Plaintiff realleges and incorporates Paragraphs 1.1 through 5.10 as though fully set forth.
6.2. At the time of manufacture and distribution, the Product had potential risks known or knowable in light of the scientific and medical knowledge generally accepted in the relevant scientific community. Anderson v. Owens-Corning Fiberglas Corp., 53 Cal.3d 987 (1991); CACI No. 1205.
6.3. The risk presented a substantial danger to persons using the Product in an intended or reasonably foreseeable manner, and ordinary consumers would not have recognized the risk.
6.4. Defendants failed to adequately warn of the risk or to provide adequate instructions for safe use.
6.5. The lack of sufficient warnings or instructions was a substantial factor in causing Plaintiff's harm.
6.6. As a direct and proximate result, Plaintiff has suffered general and special damages in amounts to be proven at trial.
7. SECOND CAUSE OF ACTION — NEGLIGENT FAILURE TO WARN
(Against All Defendants)
7.1. Plaintiff realleges and incorporates Paragraphs 1.1 through 6.6 as though fully set forth.
7.2. Defendants owed Plaintiff and other foreseeable users a duty to exercise reasonable care to warn of risks they knew or, in the exercise of reasonable care, should have known about, and to adequately test, monitor, and update warnings for the Product. See CACI No. 1222.
7.3. Defendants breached that duty by failing to provide adequate warnings or instructions, by failing to conduct reasonable testing and post-sale surveillance, and by failing to update warnings after the risk became known or knowable.

15. CALIFORNIA PRACTICE NOTES
-
Two distinct warning theories. California recognizes both strict-liability failure to warn (CACI No. 1205) and negligent failure to warn (CACI No. 1222). Plead both. They differ chiefly in that strict liability focuses on the product/warning while negligence focuses on the reasonableness of the defendant's conduct; both are limited to risks known or knowable.
-
Anderson knowability standard. Strict-liability failure-to-warn liability reaches only risks known or knowable in light of the scientific and medical knowledge generally accepted in the relevant scientific community at the time of manufacture and distribution. Anderson v. Owens-Corning Fiberglas Corp., 53 Cal.3d 987 (1991). State-of-the-art evidence is admissible. This is the signature California rule and should be pleaded expressly.
-
Learned-intermediary doctrine. For prescription drugs and medical devices, the manufacturer's duty to warn runs to the prescribing physician, not the patient. Carlin v. Superior Court, 13 Cal.4th 1104 (1996). Brown v. Superior Court, 44 Cal.3d 1049 (1988), bars strict design-defect liability for prescription drugs (comment k), leaving the warning theory as the principal vehicle. Plead causation through the prescriber.
-
Heeding inference. California permits an inference that an adequate warning would have been heeded; plead that Plaintiff (or the prescriber) would have acted differently with an adequate warning.
-
Pure comparative fault. Plaintiff's fault reduces but does not bar recovery. Li v. Yellow Cab Co., 13 Cal.3d 804 (1975); Daly v. General Motors Corp., 20 Cal.3d 725 (1978).
-
Statute of limitations. Two years from accrual under CCP § 335.1; the discovery rule may delay accrual for latent injuries. California has no general products statute of repose; long-tail claims (e.g., asbestos under CCP § 340.2) remain viable.
-
Damages pleading. CCP § 425.10 prohibits stating a specific dollar amount of personal-injury damages in the complaint; serve a § 425.11 statement of damages before default. A § 425.115 punitive-damages statement is required before a default judgment for punitive damages.
-
Punitive damages. Civil Code § 3294 requires clear-and-convincing evidence of malice, oppression, or fraud; for corporate defendants the conduct must be authorized or ratified by an officer, director, or managing agent.
-
Federal preemption. Screen for MDA preemption of PMA Class III devices (Riegel v. Medtronic, 552 U.S. 312 (2008)) and generic-drug warning preemption (PLIVA, Inc. v. Mensing, 564 U.S. 604 (2011)); brand-name warning claims generally survive (Wyeth v. Levine, 555 U.S. 555 (2009)).

About This Template
Product liability cases are brought when a defective product causes injury, either because of a design flaw, a manufacturing defect, or a missing warning. These claims are usually fought by large corporate defendants and their insurers, so the paperwork has to be thorough from the start. Well-drafted complaints and demand letters identify the specific defect, the chain of distribution, and the legal theory clearly enough to survive early motions.
