We all know that obtaining patent protection internationally requires considerable funds, the average probably being $ 5,000 per country. For an individual inventor this can be a lot of money. However, it can also tighten a company´ s budget since companies generally have to seek patent protection for more than one product. It has thus become standard practice to base the decision for international filings on an early examination report which may be obtained in the country of first filing. It has further become good practice to file an international (PCT) application before the end of one year after the first national filing, thereby claiming convention priority, instead of going directly national at the end of the priority year. If the applicant asks for an international preliminary examination (IPE), there will be a further indication about the chances of obtaining national patents prior to converting the international application into national original applications.
