METHODOLOGYTerminologies for Patent Analysis (1/2)

Patent Applicant, Patent AssigneeAn applicant is a person or organization (e.g. company, university, etc.) who/which has filed a patent application. An assignee is a person or organization (e.g. company, university, etc.)who/which holds patent rights. There may be more than one applicant/assignee per patent application.

Patent FamilyA patent family is a set of patents filed in multiple countries to protect a single invention by a common inventor(s). A first application is made in one country – the priority country – and isthen extended to other countries.

Priority DateThe priority date is the date on which the patent application was filed. At this date the patent document is not made available to the public.

Priority NumberThe priority number is the number of the application with respect to which priority is claimed, i.e. it is the same as the application number of the claimed priority document. The prioritynumber is made up of a country code (two letters), the year of filing (four digits) and a serial number (variable, maximum seven digits).

Publication DateThe publication date is the date on which the patent application was first published. It is the date on which the patent document is made available to the public, thereby becoming part ofthe state of the art.

Publication NumberThe publication number is the number assigned to a patent application on publication. Publication numbers are generally made up of a country code (two letters) and a serial number(variable, one to twelve digits) (e.g. DE202004009768).

International Patent Classification (IPC)The technical content of patent documents is classified in accordance with the International Patent Classification (IPC). The publishing office assigns an IPC symbol valid at the time ofpublication of the patent application. The complete IPC can be found on the website of the World Intellectual Property Organization (WIPO - http://www.wipo.int/ipcpub).

CitationsIn the context of patents, a citation is a reference to a previous work (prior art) that is considered relevant to the considered patent application. Citations may be made by the Inventor orby the Examiner during patent examination.

METHODOLOGYTerminologies for Patent Analysis (2/2)

WO and EP Patent ApplicationsInternational (WO) and European (EP) Patent Applications are made through the World Intellectual Property Organization (WIPO) and the European Patent Office (EPO), respectively. WOapplications designate signatory states or regions to the Patent Cooperation Treaty (PCT) and will have the same effect as national or regional patent applications in each designated state orregion, leading to a granted patent in each state or region. EP applications are regional patent applications designating signatory state to the European Patent Convention (EPC), and leading togranted patents having the same effect as a bundle of national patents for the designated states.

Legal Status of the Patent

• Pending: Patent applications in a pre-grant/pre-final-rejection stage in the patent office.

• Granted: Patents in a ”post-decision” or “post-grant” stage in the patent office.

• Abandoned (Lapsed): Patents or published applications that are not in force before the end of the normal term right because of applicant action or in-action. Normally this status refers topost-grant patents where the applicant has not paid the necessary renewal fees. However, “Lapsed” can include pre-grant published applications that are deemed likely abandoned becausethere has been no known activity in the office for a significant period of time. Typical office status for Lapsed could be “abandoned”, “lapsed”, “withdrawn”, “surrendered”, etc.

• Expired: Granted patents that have expired due to normal life of the patent cycle.

• Rejected (Revoked): Patents or published applications that are not in force before the end of the normal term right because of office action. Normally, this status refers to post-grant patentssubject to opposition events. However, “Revoked” can include final rejection notices when we have that information from the office. Typical office status for “Revoked” could be“suspension”, “interrupted”, “cancelled”, “revoked”, “refused”, etc.

Litigation Cases“Litigation Cases” refers to filed actions. A single case filed may include multiple defendants. The date for a case filed is the date on which it was originally filed.

Litigation Campaign“Litigation Campaign” refers to all cases filed by the same plaintiff (inclusive of all members in the corporate family) where each case has at least one patent or family member of a patent incommon with another case in the campaign.

ITC (International Trade Commission) InvestigationThe United States International Trade Commission (USITC) is an independent, quasi-judicial Federal agency with broad investigative responsibilities on matters of trade. The Commissionadjudicates cases involving imports that allegedly infringe intellectual property rights. A company can request an ITC investigation if they think that another company imports productswhich infringe their patents in USA . Through such proceedings, the agency facilitates a rules-based international trading system. The Commission makes most of its information and analysisavailable to the public to promote understanding of international trade issues.

• New patent applications are mainly related to inorganic andinorganic/polymer solid electrolytes, almost equivalently sulfide andoxide solid electrolytes. In fact, both of them have advantages anddrawbacks and that the choice of electrolyte material is not obvious.

• Contrary to patents on electrode and battery cells, patents onelectrolytes are equivalently related to all type of solid electrolytes.Contrary to patents on inorganic/polymer and polymer electrolytes,patents on inorganic electrolytes are equivalently related toelectrolyte, electrode and battery. Patents on electrode and batterycells related to inorganic and inorganic/polymer solid electrolytesmainly mention a list of inorganic materials.

• Garnet and Argyrodites are the main inorganic materials mentioned innew patent applications. There is only very few patents related toOxide Glass Ceramics and LISICON indicating that these materials donot attract R&D developments (either due to their technologicalmaturity or their low performances).

• Even if Hydride is an emerging solid electrolyte, several new patentpublications are related to battery cell confirming that this material isvery promising.

The numbers represent the numberof patent families. One patent familycan belong to multiple segments.

• Newly granted patents are mainly related to Electrolyte and Batterycells. There are only few new granted patents related to Battery pack(Bosch/SEEO, Samsung) and separator (LG Chem, Chinese companies).

• New granted patents are mainly related to inorganic solidelectrolytes, almost equivalently sulfide and oxide solid electrolytes.In fact, both of them have advantages and drawbacks and that thechoice of electrolyte material is not obvious. There are also numerousnewly granted patents related to inorganic/polymer and polymer solidelectrolytes.

• Newly granted patents on polymer electrolytes are almost exclusivelyrelated to electrolyte material. On the contrary, newly grantedpatents on inorganic and inorganic/polymer electrolytes are relatedto electrolyte, electrode and battery cell. Contrary to patents onelectrode and battery cells, patents on electrolytes are related to alltype of solid electrolytes. Patents on electrode and battery cellsrelated to inorganic and inorganic/polymer solid electrolytes mainlymention several inorganic materials.

• Sulfide Glass Ceramic and Garnet are the main inorganic materialsmentioned in newly granted patents. There is also numerous newlygranted patents on NASICON and Perovskites.
