*Switzerland ([http://en.wikipedia.org/wiki/Postal_codes_in_Switzerland_and_Liechtenstein Sourced from Wikipedia]): Swiss (and Lictenstein) postcodes are hierarchical four-digit numbers of the form District+Area+Route+PONumber, where districts are numbered West to East (would you expect less from the Swiss?). In the patent data Swiss postcodes are comparatively immaculately behaved with the following formats appearing: NNNN, NNNN-, CH-NNNN, CH - NNNN, CH NNNN, CHNNN, CH- NNNN, CHNNN. Though the "H" may sometimes be lowercase.

**Simple Regex: <tt>(CH|Ch|)\s?-?\s?\d{3,4}-?</tt>

*Australia: (http://en.wikipedia.org/wiki/Postcodes_in_australia Sourced from Wikipedia]): NNNN where N is a numeric. Australian postcodes should appear at the end of addresses, and are frequently preceded by the acronym for the territory/state (specifically: NSW, ACT, VIC, QLD, SA, WA, TAS, and NT). In the patent data variations include: NNNN, AU-NNNN, XXX NNNN, Xxx. NNNN X.X.X. NNNN, XXXNNNN, where XXX indicate the two or three characters of the acronym.

**Simple Regex: <tt>(NSW|Nsw|ACT|Act|VIC|Vic|QLD|Qld|SA|Sa|WA|Wa|TAS|Tas|NT|Nt|Au|AU)?(\w\.\w\.\w\.)?\.?\s?-?\s?\d{4,4}</tt>
