Why this IP story matters

Priority gives an applicant a limited window to file abroad while relying on the date of an earlier qualifying application: generally 12 months for patents and utility models, and six months for marks and designs. The Convention does not create one worldwide registration; national or regional offices still decide protection under their laws. For companies expanding internationally, recording the first filing date and tracking those deadlines can be as important as choosing the mark or invention itself.
