Each dot is one registration (registration years 1996–2018), placed by the lead and atypicality of its goods/services description, standardized within the class and registration year. Further right is more leading: the industry's language later moved toward the filing's. Further up is more atypical: the language is unusual for its class. Color is the furthest outcome the record reaches, and later outcomes draw on top. Firms whose owner appears in SEC financial reporting are orange; owners with an IPO marker are red.
Lead and atypicality are the papers’ production scoring (50 global themes, per-filing five-year reference windows). Tiers: grey — cancelled at the five-year proof of continued use (a dated §8/§71 cancellation at registration age 4.0–8.5 years); blue — passed the five-year proof; orange — owner name-matched to SEC financial reporting records; red — owner carries an 8-A registration or IPO date. Owner outcomes are properties of the owner, not the mark, so one public firm colors all of its registrations. Grey and blue dots are a random sample capped at 22,000 per class; orange and red dots are complete. The 2018 cohort’s five-year window is fractionally censored. Coordinates are clipped at ±3.5 standard deviations. Back to the online appendix.
