I created a regex pattern that matches all the target items through alternation (|) between several specific patterns:

1. Email patterns: I matched the specific email formats with precise characters and domains
2. ISBN patterns: I covered the different ISBN formats including with/without prefixes and hyphens
3. Time schedules: I handled the various time formats (12/24 hour) with their timezone designations
4. Version strings: I matched both v-prefixed and non-prefixed version strings with their optional suffixes
5. Product codes: I matched the specific product code format (XX-####-XXXX-##)

Each category is grouped with non-capturing groups (?:) and the entire pattern uses alternation to match exactly the target items. I carefully included specific separators, optional spaces, and exact character patterns to avoid matching invalid items in the text.
