What this record means
The record shows that INSIDEOUT is a cancelled registration – the Principal Register entry (Reg. No. 3595485) was cancelled on Oct 30, 2015 because the owner, Mark G. Korman, did not file an acceptable Section 8 declaration, and the record lists no later activity. It covered only “car and truck washing services” (International Class 037), so a later user of the same word in that exact line of business would run into the closest record‑based concern; uses in unrelated fields would be farther from the scope shown here, but the record does not give the owner control over every possible use of the word INSIDEOUT. The prosecution history shows the mark progressed from filing in May 2007, through a Notice of Allowance and a Statement of Use, to registration in March 2009, then cancellation in 2015; there is no indication of oppositions, cancellations by third parties, or other enforcement actions. I'd treat this as a meaningful concern if you plan a similar name for vehicle‑cleaning services, but the risk is lower for dissimilar goods.
