IFI Patent Status


The ifi-patent-status container includes IFI's calculated legal status and expiry dates. We provide a simple view of the current estimated status of a patent or application as well as the expected expiration date.

Note: We calculate the patent status for EP designated states, and we recently changed how we do this. Prior to May 22, 2017 we followed method 1, and beginning on May 22 we reloaded these records in order to follow method 2.

ifi-integrated-content/ifi-patent-status

AttributeDescription
anticipated-expirationAnticipated expiration date is calculated according to the patenting authority and document kind and reflects the maximum life of the patent assuming maintenance fees are paid and term extensions are not in place. See Anticipated and Adjusted Expiration Dates for more information.
adjusted-expirationAdjusted expiration date contains a date calculated to reflect term adjustments made by the Australian patent office or by the USPTO under 35 USC 154. Present for AU and US only. See Anticipated and Adjusted Expiration Dates for more information.
regulatory-extension"Yes" when true. This field appears in AU or US records when exploitation of a patent is delayed by regulatory review (e.g., FDA review) or in other patents when a Supplementary Protection Certificate (SPC) has been issued for a patent.
terminal-disclaimer"Yes" when a notice of terminal disclaimer is present. For US pre-2001, the adjusted-expiration date may incorporate a terminal disclaimer; post-2000, the adjusted date does not include the effect of a terminal disclaimer.

ifi-integrated-content/patent-status/ifi-patent-status-description

Current patent status is calculated by sequential analysis of the Inpadoc legal status events. It is recalculated whenever an Inpadoc update is received.

AttributeDescription

IFI Standardized Names


The ifi-standardized-name container provides IFI's standardized assignee and applicant names. We map name variants and common misspellings under one easily searchable name so, for example, your search for "Microsoft" will also find documents assigned to "Mircrosoft" or "Mircosoft". IFI standardized names are available for original and current assignees. In addition, we provide probable assignees for US applications and grants with no assignee.
