In the mid-nineteenth century, the emergence of synthetic organic chemistry presented English courts with an unprecedented dilemma regarding chemical patents. Under traditional common-law jurisprudence, patent protection for a "manufacture" was anchored to physical artifacts whose novelty was inextricably linked to their mechanical fabrication. When synthetic alizarin—a dye chemically indistinguishable from the natural colorant extracted from madder root—was first laboratory-synthesized, judicial authorities refused to grant exclusive rights encompassing the molecule itself. Instead, early rulings strictly constrained patent grants to the specific artificial synthesis pathway disclosed in the patent specification. Consequently, rival industrial chemists who subsequently devised alternative catalytic pathways to synthesize the identical compound remained immune from infringement actions. This judicial posture persisted until late-nineteenth-century statutory revisions decoupled the patentability of synthesized chemical compositions from their specific preparation methods, provided that the artificial substance was not already accessible in a natural state.

Which of the following statements regarding early English patent protection for synthetic dyes is most strongly supported by the passage?

  1. A
    Chemists who developed alternative catalytic routes to synthesize alizarin typically achieved greater commercial profitability than the inventors who created the initial synthesis.
  2. Prior to the late-nineteenth-century statutory revisions, an inventor who held a patent for a synthetic dye could not legally bar a competitor from selling the identical chemical compound if the competitor employed a different method of synthesis.Cevap
  3. C
    Under the late-nineteenth-century statutory revisions, synthetic alizarin would have automatically qualified for composition-of-matter patent protection regardless of whether madder root was widely harvested.
  4. D
    The refusal of English courts to protect chemical molecules per se was largely driven by pressure from foreign textile manufacturers seeking cheap domestic access to synthetic mordant dyes.
  5. E
    Traditional English common-law jurisprudence granted patents for natural agricultural extracts under the same legal standards applied to mechanical inventions.

Cevap

Prior to the late-nineteenth-century statutory revisions, an inventor who held a patent for a synthetic dye could not legally bar a competitor from selling the identical chemical compound if the competitor employed a different method of synthesis.
The correct answer accurately synthesizes the passage's explicit statements: early rulings restricted patent rights solely to the disclosed synthesis method, and competitors using alternative catalytic pathways to make the identical compound were immune from infringement suits. Therefore, holding an early patent did not grant the power to stop competitors from selling the exact same substance when made through an alternate route.

Adım Adım Çözüm

1
Analyze the passage premises governing early patent scope
The text establishes that early English courts constrained patent grants strictly to the specific artificial synthesis pathway disclosed by the inventor, rather than the resulting molecule itself.
Identifying the legal boundaries established by the courts is necessary to evaluate the scope of exclusivity.
2
Evaluate the legal consequence for competitors manufacturing the same compound
Competitors who devised alternative catalytic routes to produce the identical compound were explicitly immune from infringement actions.
This establishes that the identical end substance could be legally commercialized by third parties using distinct processes.
3
Synthesize the temporal condition with the legal consequence
Before statutory revisions altered this standard in the late nineteenth century, a patentee could not prevent competitors from selling the identical compound if produced via a non-infringing synthesis method.
Directly matches the logically entailed conclusion required for an LSAT reading comprehension inference.
