The strategies of technology providers for obtaining the essentialpatents based on the analysis of 3G/4G declared essential patents andpatent pool patents are studied. According to the results, the number of the essential patentsowners is getting large and the dominant firms are losing their forces forthe standards, so the standards tend to be the commons. Therefore, thestandardizations are good chances for innovative technology providers. Technology providers are classified into the three types. Type Iplays the role of only providing technologies related to the standards,type II providing the technologies and producing intermediate goodslike chipsets, and type III providing the technologies and the endproducts. It is showed that type I/II obtain essential patents throughadvanced R&D before standardization, while type III obtains themthrough strategic R&D during standardization. It is also discovered thatobtaining of essential patents is related to the technologicalcontributions for type I/II, while it is related to the market contributionsfor type III. Therefore type I/II should focus on innovative advancedR&D, while type III should make efforts to actively participate instandardization and increase market share of the products in order toeffectively obtain essential patents. This paper also suggests strategies of technology providers forobtaining the essential patents through analysis of the successful essential-patent business cases. Essential patents are only a value-addedprocess for type I, so what to research is the most important for it. Standard technology is classified into the ‘general element technology’which can be commonly applied to other standards of the same or thesimilar fields, and the ‘standard specific proprietary technology’ whichis only used to the specific standard. It is better for type I/II to focus itsresearch on the general element technology, because it is clearlyappraised and adopted to the standard from a view point of onlytechnology. On the other hand, it is better for type III to focus on thestandard specific proprietary technology, because it is adopted accordingto the influence and agreement between firms.
