WTO actions are very expensive and likely require a commitment on the part of the affected countries' governments to pursue.
Easy way out...
The clone manufacturers first response to a ruling will be 'we promise' to stop manufacturing clone product. Given 90 days by trade ruling to comply. (We don't want to destroy livelihoods, and 2 million parts already in distribution channel...!)
Key point: Specific high-tech components only have a lifespan of a couple of years between major revisions anyway, and the original action took over 12 months to frame in legalese, and pass through the various governments / parties...
Clone manufacturer starts tooling up for rev.2, and takes 120 days to shutdown the rev.1 distribution (ahh sorry, hard to get new supply chain running... very sorry). Excess stock is recalled and dumped to untraceable Shenzen market traders (at cost - no loss). These appear in your pet collar trinkets, and third tier unbranded junk.
Two months later, the manufacturers have complied with the trade ruling, and created a newer, more profitable channel with rev.2 for the next 18 months.
P.S. This adds to the sell price of the OEM product - so they have any chance of making any return within the ramp-up period.
Governments and first-world society are suckers for a story.
