| 35 USC 184 |
Some countries only impose restrictions on inventions with military or nuclear importance, while others take an equally dim view if a novelty musical toothbrush is the subject of a patent application filed abroad without permission.

Advice from a competent Freedonian patent attorney is the safest bet, providing that you're not up against an urgent deadline, and time zones permit, and you have confidence that you are indeed asking someone competent.
If for some reason you can't contact a Freedonian colleague, information is surprisingly hard to find. The Freedonian Patent Office website, for instance, may give meticulous detail on all of the charming local filing requirements, e.g. forms notarised to apostille, drawings on Bristol board (remember that?), and a triple-spaced specification printed on lemon-coloured rice paper in 12.5 point Comic Sans font. But many patent office and patent attorney websites carry no guidance on whether local laws allow you to bypass their services entirely by filing abroad.
This Kat has been unable to find any comprehensive listing of all the countries that do have foreign filing restrictions or licence requirements, and perhaps more useful, a "whitelist" of the very many countries that have no such restrictions. The latter might be more useful because if your only foreign inventor is (say) Irish and you can see from a reliable list that Ireland has no foreign filing restrictions - and this Kat can reassure you that Ireland has no such restrictions for its nationals or residents - you're home and dry and can file where you please subject to your local laws.
Some online resources list the better known countries that do have some restrictions, with the USA, UK, France, Germany, China, South Korea, India, Canada and New Zealand all being mentioned as having some level of restriction, though the requirements vary widely. Some of the "whitelist" countries with no restrictions mentioned on the same listings include Japan, Mexico, Taiwan and Australia.
That brief summary has not been verified, and it leaves unmentioned eight of the G20 nations, most of the EU, and the vast majority of the WTO countries - an enormous knowledge gap (represented by the white area on the map below). Enormous for an attorney under pressure perhaps, but surely our readers know of a more comprehensive listing, or collectively the IPKat community can crowdsource a list of which countries do and don't have a foreign filing licence requirement?

Readers may recall the main dispute, handed down on 31 March 2011 (

The product for which Ranbaxy sought its declaration was formed from a starting material of magnesium esomeprazole with an optical purity of ≥ 99.8 % e.e. To this was added a quantity of omeprazole racemate. The resultant product accordingly no longer contained magnesium esomeprazole of that optical purity.
Ranbaxy contended that this was limited to use of magnesium esomeprazole with an optical purity of ≥ 99.8% e.e. for the manufacture of a medicament which contains magnesium esomeprazole of that purity. AstraZeneca, however, argued that this was a simple process claim and that as such, it was not limited to the manufacture of specific products but extended to the use of the claimed process to make any product. Accordingly, it stated that the claim covered use of a magnesium salt of esomeprazole with an optical purity of ≥ 99.8% e.e. for the manufacture of a medicament for the inhibition of gastric acid secretion irrespective of whether or not the medicament itself contained magnesium esomeprazole at all.

Evidently, there were some patents. The precise relationship between them requires this diagram (left) to explain. The patents were owned jointly by MedImmune and MRC, who alleged that they had been infringed by Novartis’ sales of ranibizumab, a pharmaceutical product sold under the trade mark Lucentis and is approved for the treatment of an eye condition known as wet age-related macular degeneration. Novartis counterclaimed challenging the priority of the patents, and also threw the invalidity kitchen sink at the claimants by alleging obviousness and insufficiency as well as challenging it on the basis of added matter.The Judge commenced his discussion of the law by identifying the skilled person – a team a team consisting of an immunologist and a molecular biologist with some experience in antibody engineering/protein chemistry/cell biology. He then considered the duties and responsibilities of the expert witnesses, noting that:
