IANAL however:
The term is a generic term "widget cleaning manchester" and not something like "The manchester widget cleaning corp"
I would say that it is very unlikely they could do anything since they are generic. Just think of this, I constructed a site for a friend who owns a popular local hotel and bar. Of course with it being a hotel there are also many other UK hotels scattered about using the same name yet only one hotel got:
keyword1keyword2hotel.co.uk, only one got
thekeyword1keyword2hotel.co.uk, only one got
keyword1keyword2hotel.com, only one got
thekeyword1keyword2hotel.com
All the other several hundered hotels in the UK have all adopted a satandardisation of:
keyword1keyword2town.co.uk
or
keyword1keyword2hoteltown.co.uk
I have also constructed some photographers sites doing similar:
specifictownphotographer.ccTLD
or
specifictownphotography.ccTLD
It would be interesting to know how they base their rights to the .co.uk when they didn't have the nous to register it themselves in the first place!
What do they cost GBP 5-10 per annum, unbelievable?
