Gold-Plating Equipment for Small Precision Parts
Rejection revoked, then grant
The response showed that complexity was necessary, not over-design.

EXAMINER LOGIC
How the rejection framed the case
The examiner combined a curtain-hook electroplating device with a plate-type plating rack, treating the rotary grid, independent holes, and gear transmission as obvious. The conductive component was criticized as unnecessarily circuitous and complex.
FIP RECONSTRUCTION
How the response rebuilt the case
We reframed the problem as a compound engineering challenge: physical isolation of soft deformable parts, stable dynamic conduction, and precise transmission in a corrosive electrolyte environment. The complexity was not over-design; it was necessary. We then proved incompatibility of D1/D2 in workpiece type, operating environment, power supply, and technical route, while forcing evidence for alleged common general knowledge.
OUTCOME
What changed procedurally
The reexamination board revoked the rejection; the case returned to examination and was granted. It is a model case for problem reframing, motivation-to-combine blocking, and burden-of-proof pressure.
Deep technical note
Detailed English-only prosecution analysis.
This section expands the case beyond the homepage summary so foreign counsel can assess the reasoning pattern, not just the outcome.
Diagnostic read
- The examiner combined a curtain-hook electroplating device with a plate-type plating rack and criticized the conductive path as circuitous.
- That criticism assumed the problem was simple: fixing each plated part during electroplating.
- The real problem was more demanding: isolate soft precision parts, maintain dynamic conduction, and achieve precise transmission in a corrosive environment.
Response architecture
- Rebuild the problem as a compound engineering challenge rather than a simple fixture design.
- Prove incompatibility between the cited references in workpiece type, operating environment, power supply, and mechanical route.
- Require evidence for alleged common general knowledge when the examiner relied on unsupported routine-means assertions.
Due-diligence takeaways
- Complex structure can be the necessary answer to a complex technical problem.
- A rejection can be reversed when the examiner has simplified the industrial environment too aggressively.
- Burden-of-proof pressure is useful when common knowledge is asserted without evidence.
What a peer firm can test
For a live matter, we normally ask for the relevant patent office or jurisdiction, prosecution stage, core rejection issue, principal cited references, current deadline, and a neutral technical summary. Client names and unpublished full documents can wait until NDA and conflict clearance are complete.
The first review focuses on whether the examiner has mis-modeled the technical problem, overstated a motivation to combine, relied on unsupported common knowledge, or missed an allowance route available through disciplined claim amendment.
