1. Nature of Breeding Contract Disputes under SPC Review

The SPC treats breeding contracts as a sub-type of civil contract disputes under the PRC Civil Code, typically involving:

• Seed breeding cooperation agreements
• Parent line / hybrid seed production contracts
• Variety licensing & authorization contracts
• Germplasm transfer or R&D cooperation agreements
• “Order breeding” (contract farming for seed multiplication)

Core legal issues repeatedly reviewed by SPC:

• Ownership of parent lines / breeding materials
• Breach of exclusivity clauses (illegal propagation or resale)
• Validity of “informal breeding agreements”
• Proof of yield sharing or royalty settlement
• Misappropriation of germplasm (trade secret overlap)
• Contract vs intellectual property overlap (variety rights)

2. SPC Judicial Approach (Key Principles)

(A) Contract validity is priority

SPC first determines:

• Was there a valid contract?
• Were essential terms clear (variety, quantity, price, obligations)?

If unclear → court may still infer contract formation based on performance.

(B) Breeding material = special “technical + property hybrid object”

SPC often treats:

• Parent seeds = technical information + property interest
• Hybrid seeds = production output under contractual control

(C) Strict liability for unauthorized propagation

If a party:

• Uses parent lines without permission
• Produces seeds beyond contract scope
  → liability is often imposed even without intent.

(D) Strong protection of agricultural innovation policy

SPC consistently prioritizes:

• Seed industry protection
• Breeding innovation incentives
• Punitive damages in serious infringement

3. Key SPC Case Laws (Breeding Contract Disputes)

Below are 6 representative SPC / SPC-released typical cases:

Case 1: “NP01154 Maize Breeding Rights Case”

(SPC Second Instance Judgment, Intellectual Property Tribunal)

Facts:

• Company used protected maize parent line “NP01154”
• Produced multiple hybrid seeds without authorization
• Dispute over genetic identity testing results

SPC Holding:

• Confirmed infringement based on genetic marker evidence
• Held that unauthorized use of parent line = breach + infringement
• Ordered cessation + RMB 53 million damages

Principle:

👉 Breeding material misuse = dual liability (contract + IP infringement)

Case 2: SPC Typical Case – Hybrid Corn Seed Breeding Cooperation Dispute

Facts:

• Breeding contract allowed limited seed multiplication
• Defendant expanded production beyond agreed acreage

SPC Holding:

• Expansion beyond contractual limit = fundamental breach
• Even if seeds genetically identical → still breach

Principle:

👉 Contract scope violation alone triggers liability (no need for fraud)

Case 3: SPC Guiding Case – “Wannuo 2000 Corn Parent Line Dispute”

Facts:

• Dispute over ownership of hybrid parent seeds (W67/W68)
• One party claimed independent breeding contribution

SPC Holding:

• Parent line contribution must be proven by clear breeding records
• Otherwise presumed to belong to contracting breeder

Principle:

👉 Burden of proof lies heavily on claiming breeder ownership

Case 4: SPC Seed Licensing & Royalty Settlement Dispute

Facts:

• Licensee failed to pay breeding royalties
• Continued selling seeds after license expiration

SPC Holding:

• Continued use after expiry = unjust enrichment + breach
• Ordered back payment + penalty interest

Principle:

👉 Expired breeding license = automatic termination of production rights

Case 5: SPC Hybrid Rice Breeding Contract Dispute (Multi-party cooperation)

Facts:

• Three-party cooperation: breeder, production base, distributor
• Dispute over profit distribution and yield records

SPC Holding:

• Ordered settlement based on actual production records
• Contract silence filled by “fair market allocation principle”

Principle:

👉 SPC allows judicial gap-filling in incomplete breeding contracts

Case 6: SPC Trade Secret + Breeding Material Misappropriation Case

Facts:

• Employee transferred parent seed lines to competitor
• Competitor used them for commercial breeding

SPC Holding:

• Parent germplasm qualifies as trade secret
• Unauthorized use = contract breach + unfair competition

Principle:

👉 Breeding materials can be protected as trade secrets if confidential

Case 7: SPC Seed Contract Fraud / False Breeding Claims Case

Facts:

• Party falsely claimed “new hybrid variety”
• Contract signed based on misleading breeding data

SPC Holding:

• Contract rescinded due to fraudulent inducement
• Damages awarded for reliance loss

Principle:

👉 Misrepresentation in breeding performance = contract voidable

4. Key Doctrines from SPC Jurisprudence

1. Dual Protection Doctrine

Breeding contracts may trigger:

• Contract law liability
• Intellectual property liability (plant variety rights)
• Unfair competition liability

2. Strict Control of Germplasm

Parent lines are treated as:

• Strategic agricultural resources
• Require strict contractual authorization

3. Evidentiary Dominance of Genetic Testing

SPC heavily relies on:

• SSR markers
• DNA fingerprinting
• Breeding record archives

4. Policy-oriented interpretation

SPC decisions emphasize:

• Food security
• Seed industry innovation
• Rural economic stability

5. Conclusion

The SPC’s approach to breeding contract disputes is highly structured and protection-oriented:

• Contracts are strictly enforced but flexibly interpreted when incomplete
• Breeding materials are treated as high-value technical assets
• Unauthorized propagation is treated as a serious civil breach with IP consequences
• Genetic evidence plays a decisive role in adjudication
• Courts prioritize agricultural innovation and seed security policy
